Sarah Snook is forming her own line of succession. 

The Succession star, 35, has welcomed her first child with husband Dave Lawson. Snook announced the little one's arrival by sharing a picture of herself watching the series finale of the HBO drama to Instagram May 29, and fans spotted what appeared to be the top of a baby's head in the photo.

"I just watched the final episode of the final season of something that has changed my life," she wrote in part of her post. "And now, my life has changed again. Thank you for all the love and support." 

E! News has reached out to Snook's rep for comment but has yet to hear back. 

The news comes one day after Succession's four-season run came to an end (we won't include any spoilers here, but you can read the recap to find out what happens to the Roy family and their media empire).

Earlier in her post, Snook—who played Shiv Roy—tried to put her experience on the Emmy-winning series into words.

"It's hard to express what this show has meant to me," she wrote. "The places I got to go, the immense talent I got to work with…it breaks my heart that it is all over. But my heart had to be this full of all the memories, good times, challenges and triumphs, to be able to break at all…so that makes me grateful. To have been blessed to join this crazy adventure of a show will be a career highlight, which will no doubt be hard to top."

The actress also expressed her gratitude for the cast and crew.

"I am so, so proud and humbled by everyone's hard work season after season: we all set the bar high for each other, then exceeded it and excelled, in every department," she added. "The friendships, the scripts, the locations, the one liners, the early mornings, the last minute changes, all the highs and lows: I'm going to miss it all. The people of this show are a talented bunch, and I'm proud to have worked alongside them, it's the people I will miss most of all."

Fans learned that Snook was pregnant after she debuted her baby bump on the red carpet of the Succession season four premiere in New York in March. However, the Golden Globe winner said you couldn't really tell she was growing her family while filming the show.

"You couldn't tell," she told Entertainment Tonight at the premiere, before talking about her baby bump. "It's not super big at the moment."

During an interview with Today that same month, Snook revealed the baby was due mid-May and that she was waiting until after the birth to find out the sex of the child.

The bundle of joy comes about two years after Snook—who previously shared on The Tonight Show that she also has a stepson—tied the knot with Lawson.

"At the beginning of the pandemic last year, I got locked down in Melbourne with one of my best mates and we fell in love," she told Vogue Australia in 2021. "We've been friends since 2014, lived together, travelled together, always excited to see each other, but totally platonic. We've just never been single at the same time. I proposed and we got married in February in my backyard."

Logan Roy, media mogul and father of four adult kids who are each unhappy in their own way, is on his third marriage, with the occasional other woman popping in and out of his bedroom.

Cox, 76, is also a father of four: Son Alan, 52, and daughter Margaret, 45, with Caroline Burt, who he was married to from 1968 to 1986, and sons Orson, 21, and Torin, 18, with his second wife, Nicole Ansari-Cox.

"I was just in my twenties when I got married to Caroline," the Scottish actor wrote in his 2021 memoir Putting the Rabbit in the Hat. "Far too young. But I wanted the stability of marriage and kids. I wasn't one of those middle-class actor-types, taking drugs and letting it all hang out."

He called Ansari-Cox, an actress and theater director, his "soulmate." She also, incidentally, made a winning cameo at Logan Roy's funeral as Sally-Ann, his mistress from his second marriage to Caroline (Harriet Walters), who jollily introduces the newcomer to Logan's third wife Marcia (Hiam Abbass) and his most recent girlfriend Kerry (Zoe Winters) as her Kerry.

As the poor little rich boy no one seems to expect anything of, Logan's eldest son Connor, from his first marriage, wavers between being the least nasty and most delusional of the siblings. The aspiring presidential candidate finally got to marry former escort Willa, who sorta likes him but mainly appears to be tolerating him—but accepting his largesse and promising not to leave today is kinda like love, right?

In real life, Ruck and first wife Claudia Stefany share daughter Emma, 35, and son Sam, 28. The 66-year-old is also dad to daughter Vesper, 12, and son Larkin, 8, with The Killing star Mireille Enos, his wife since 2008. 

Enos and a newly divorced Ruck met while doing a play together in New York. The first time she saw her future husband, Enos told People, "Alan walked in the door and my brain said, 'Oh, there he is.' It was a moment of recognition of some other person who was going to change my life."

It's easy to forget Kendall Roy is a separated father of two young kids because he'd been so wholly consumed with taking his dad down.

In real life, Emmy winner Strong is still a bit of a jet-setter, but navigating friendlier skies: The 44-year-old and his wife since 2016, Emma Wall, split their time between homes in New York and her native Denmark. They're also parents of three daughters, ages 4, 3 and 18 months.

"He does a really good job of maintaining what he's doing," Wall told the New Yorker about her famously intense-on-the-job husband in 2021, "but also creating a space for the family and a normal life."

Siobhan "Shiv" Roy isn't entirely sure why she got married, either, other than it seemed like a respectable move and she felt some sort of love-like emotion for Tom Wambsgans. And now those chickens are coming home to roost, with Tom ending season three on Team Logan and shanking his wife with the proverbial shiv, just as the Roy siblings seemed poised to get the better of their father.

Snook's domestic situation feels more hopeful. "I'm in bliss," the Australian actress told Australian Vogue in 2021 after quietly marrying comedian Dave Lawson, her longtime "best mate" whom she fell in love with during pandemic lockdown.

"It's been a ride," she acknowledged. "There's so much heartache and sadness in the world, but on a micro personal level, I've been very fortunate."

The 35-year-old confirmed in March that she's pregnant with their first child, and she's way more delighted about it than also-expecting Shiv. Snook and Lawson welcomed the child in May.

Poor Tom Wambsgans, who thought he was hitting the jackpot, marrying the woman of his dreams, Shiv Roy, and securing himself an executive post in the family business, Waystar RoyCo. Alas, his wife broached the topic of non-monogamy hours after they said "I do" and the possibility that he'll end up drinking prison toilet wine continues to linger in the background.

But really the 48-year-old English actor—who won a Best Supporting Actor Emmy for his efforts in 2022—is doing quite well, married to actress Keeley Hawes since 2004, stepdad to her son Miles, 22, and father to their daughter Maggie, 18, and son Ralph, 16.

"It was a bit bumpy at the time," Macfadyen told the New York Times in 2023 about the beginning of his and Hawes' relationship (a headline-making extramarital affair on her end), "but it's fine now."

To say Roman Roy has intimacy issues would be a bit of an understatement.

But Culkin, 40, will celebrate 10 years of marriage with wife Jazz Charton on June 8, 2023, and they're parents of a 3-year-old daughter and a 19-month-old son together.

That being said, he does have a bit of a mouth on him, not unlike his quick-witted character.

When Culkin met his future wife at a bar in New York, he recalled to The Hollywood Reporter, "I said, 'I'm Kieran. You have an English accent. What's your name?' She said, 'Jazz.' I said, 'J-A-Z-Z, like the music?' And she said, 'Yeah.' And I said, 'Well, that's f--king stupid.'" (We're guessing he said that with a certain Romanesque charm because, reader, she laughed.)

Let's just say, Gerri Kellman isn't exactly helping Roman with his intimacy issues, but the release he gets from being chastised by a successful older woman certainly fits the profile.

Succession is actually a reunion of sorts for Smith-Cameron, 65, and Culkin, who both appeared in her husband Kenneth Lonergan's 2011 film Margaret. She's been married to the filmmaker since 2000 and they're parents to daughter Nellie, 21.

Cousin Greg started off just wanting to get his foot in the door at his great-uncle Logan's company, but pretty soon he's shredding documents and serving as Tom's verbal punching bag/only friend, and that leaves very little time for awkwardly hitting on models.

Braun, now 34, told the New York Times in October 2021 that he was hoping to be in his first long-term relationship one day—and then probably had to move and change his number after every single woman in the tri-state area came looking for him.

"I do believe it'll happen at the right time with the right person," said the actor, who was also writing what he described as a "relationship traumedy" when not busy filming. "Until then, it's fun to meet people and see what works."

The British writer-producer's crafty mind may have created Succession, but at home he's just a fellow who's lived, as the New Yorker reported in 2021, "in the same unflashy part of South London for almost three decades" with his wife and their two kids.

Armstrong, 52, met his missus when they were both students at University of Manchester and she works for the National Health Service.

"We might do a new kitchen," the five-time Emmy winner told the magazine. "So that will be corrupting."
