Matt Bomer’s Son Walker, Billie Lourd’s Sister Ava Bozzi Attend Prom

Ava Bozzi and Walker Halls’ prom was a family affair.

The 18-year-olds attended their high school prom together over the weekend, with their parents—Bruce Bozzi and Bryan Lourd, as well as Matt Bomer and Simon Halls, respectively—by their side to celebrate the occasion.

Bruce shared a photo of the group posing together on April 19, revealing that the pic was snapped by Ava’s “proud sister” Billie Lourd, Bryan’s daughter with late ex Carrie Fisher.

In the pic, Matt, 48, and Simon, 62, stood beside Walker, who wore a traditional black tux and a white boutonniere, with their arm around their son.

On the other side of Walker was Ava, who wore a beige strapless gown bedazzled with diamond studs and a black ribbon sash at the waistline. She stood next to Bruce and Bryan, as they all smiled for the camera.

“Prom Power!” Bruce captioned the Instagram shot. “Proud Parents!”

Bruce also included the Pride flag emoji in his caption, as well as the hashtags, “#marriageequality #surrogacy #ivf.”
