All's fired up on the Western front.

The Yellowstone universe has its first real-life couple, y'all! Two of the Paramount drama's stars Ryan Bingham and Hassie Harrison—who play love interests Walker and Laramie—confirmed their relationship with a PDA-packed photo that definitely would've made the Dutton Ranch crew do a double-take. And fans were quick to set the comments section of the April 13 Instagram post ablaze, with one user writing, "When I first saw you guys on screen together I thought you guys were perfect. I'm rooting for you guys all the way!" 

Still, Ryan and Hassie's new love isn't TV audiences' first rodeo with co-stars' chemistry leading to off-screen love. In fact, there are several couples blending work and play, including Sex/Life's fan-favorite pair, Tell Me Lies' main duo and a husband-wife have worked on three series together. Plus, a longtime private pair from Netflix's Manifest recently went public with their relationship in a "special" way. 

Read on to find out which TV co-stars are together IRL: 

No wonder those Sex/Life scenes are so steamy: Its main couple fell in love while filming season one of the Netflix drama. Sarah and Adam went public with their romance in December 2020, with fans loving their adorable displays of affection on social media. 

And mixing business and pleasure has been easy for the couple, with Sarah exclusively telling E! News that working with her boyfriend is "one of her favorite things." As she put it, Adam is one of her "all-time favorite scene partners."

"With him, it's just that easy," she explained. "I just have to look at him and 99 percent of my work is done for me. I'm falling in love with the person in real life, but I'm falling for the person on camera. It just created that extra bit that seeped through the lens. Maybe that's what people loved so much."

As for Adam, he was equally as quick to gush over his girlfriend.

"Outside of how I feel about her personally, she's such an incredible talent that I'm watching and I'm learning," he stated. "To be able to work with someone of her caliber, I feel very lucky, fortunate. But then also, I love her so much. There's a lot of layers to it."

After viewers binged the Hulu drama Tell Me Lies, they couldn't help but wonder if Grace and Jackson's onscreen chemistry had trickled over into real-life, with the pair fully playing into their are-they-or-aren't-they dynamic in interviews and on social media. And in November of last year, we finally got the answer: No, we're not fibbing, the problematic onscreen pair is together in real-life and, fortunately, toxin-free!

Jackson confirmed their romance with several photobooth snaps from the 2022 CFDA Awards, including a picture of the co-star couple kissing.  He then posted a photo of himself and Grace touching tongues with the caption, "if we kiss can we get a s2 @hulu." Spoiler alert: It worked! Tell Me Lies is set to return later this year. 

Yellowstone fans were yelling "Yee-haw!" when the co-stars confirmed their relationship with a fiery photo posted to Ryan's Instagram April 12, the two were seen sharing a kiss in front of an open flame, with the actor captioning their PDA post, "More than a spark." As for Hassie's reaction? She commented, "I love you, cowboy."

Their romance comes nearly two years after the "Weary Kind" singer split from his wife Anna Axster, with whom he shares three children. As for Hassie, she was previously linked to One Tree Hill actor Austin Nichols.

The couple that stays together continues to work together.

Married since 2020, Melanie is welcoming her husband into the Yellowjackets universe in season two as the Parenthood actor has been cast in a secret role on the Showtime series.

"I can't say anything about it, but he did an episode," Melanie exclusively told E! News at the 2023 Independent Spirit Awards on March 4. "It's always so fun to be with him. He's such a nice person, he made me look better."

However, this isn't the first time the pair has had this arrangement as Jason made a surprise cameo in Melanie and Jessica Biel's 2022 Hulu miniseries Candy, along with the latter's husband Justin Timberlake, and he appeared as a background extra in Melanie's standout episode of the HBO zombie drama The Last Of Us.

Happy wife, happy Live!

After countless appearances from Mark as a guest co-host over the year, the beloved couple made their debut as the permanent co-hosts of the morning talk show April 17, with Kelly vowing they would front the show together "until one of us dies."

But sipping a cup of coffee with millions of viewers each morning isn't the first time Mark and Kelly have shared the screen together, having met and fell in love when they played love interests on All My Children. Twenty-six years of marriage, three children—Michael, 25, Lola, 21, and Joaquin, 20—and lots of TMI revelations later, their Live! gig is a dream come true for the pair. 

"This is my favorite hour of television every morning, I swear," Mark said during their debut show. "I'm so proud, and it's just a privilege to be here with you."

While fans are already in mourning over the impending series finale of Manifest, they can take comfort in knowing two of the Netflix drama's stars have found love. 

First linked in 2020 when Page Six reported that they were dating, J.R. and Melissa finally confirmed their IRL relationship when she shared photos from their "incredibly special" vacation to Fiji in December of last year.

Netflix may have canceled Fate: The Winx Saga after two seasons, but Abigail and Danny's relationship is still going strong. The co-stars—whose characters Bloom and Sky were the supernatural drama's main couple—confirmed their romance on Instagram in November 2021.

We are still waiting for the Hallmark Channel movie based on the sweet love story between two of the network's actors. 

Dating since 2020, Kevin and Kayla do not play a couple on their hit series When Calls the Heart. But they did appear as love interests in two 2022 films: In Feeling Butterflies and My Grown-Up Christmas List.

"Believe it or not, there's no clause in my contract that says I only do movies with him—I just enjoy working with the guy," Kayla said in an interview with MediaVillage. "Hallmark is a wonderful part of my life, and I'm so grateful for everything, and for all the experiences that they've brought my way."
