Matt Bomer's Son Walker Goes to Prom With Billie Lourd's Sister Ava

Matt Bomer's son andBillie Lourd's sister were all smiles while attending prom together.

"Prom Power! Proud Parents!🏳️‍🌈," Bryan Lourd's husband, Bruce Bozzi, wrote via Instagram on Sunday, April 19, alongside a photo of the group standing in a line.

Matt stood beside husband Simon Halls and son Walker in the image, as Bozzi and Bryan wrapped their arms around daughter Ava. Walker looked dapper in a tux while Ava stunned in a strapless gown with a sweetheart neckline and a black ribbon sash.

Bozzi noted that Billie snapped the image of the group. "@mattbomer @halls.simon #bwl 📸: @praisethelourd : proud sister #marriageequality #surrogacy #ivf," he continued in the caption.

In the comments section, Billie wrote, "Our lil gal is all grown up I could weeeeeeep ❤️🥹👸🏼🥹❤️." Andy Cohen added, "Couldn't love this pic more."

Matt and Simon, who tied the knot in 2011, are parents to Kit and twins Walker and Henry. Matt, for his part, has given fans glimpses of parenthood through the years.

"I feel really lucky that I can say it's our kids because they're all teenagers now and I can still say that it's them," Bomer told Forbes in 2023 when asked what brought him the most joy in his life at the time. "I think it's a joy to hear about their lives and what's going on with them and be a part of a family. I think that's an amazing, miraculous thing and I love our boys very much."

Bryan, meanwhile, married Bozzi in 2016 and legally adopted Ava. He is also dad to daughter Billie, whom he welcomed with late actress Carrie Fisher. (Fisher died in December 2016 after a sudden cardiac arrest. She was 60.)

In November 2025, Billie shared a sweet Instagram post commemorating a milestone birthday for Ava while sharing throwback images of the duo.

"💕👯‍♀️💕My magical lil sis is not so lil anymore?! She's 18?!!!! What is time?!!" Billie wrote at the time. "The day I met her was one of the greatest days of my life. I always dreamed of having a sister and she is dreamier than any dream I could have ever had. She is the funniest, kindest, hottest, most grounded soul of a human and I am so proud / emotional af / greater than grateful to get to call her my sister. 💕 HAPPY BIRTHDAY AVA!!!"

Bruce wrote in the comments section, "We Love You!!! 💖💖."
