Brad Pitt at Jennifer Aniston’s 50th Birthday Party Pictures

Jennifer Aniston is turning the big 5-0 on Feb. 11, and got a head start celebrating the major milestone with a high-profile birthday party at the Sunset Tower Hotel in LA on Saturday night. The bash brought out A-list pals like Gwyneth Paltrow, Barbra Streisand, Demi Moore, Kate Hudson, and Ellen DeGeneres, but the attendance of one star might have you especially shook; Jennifer’s ex husband, Brad motherf*cking Pitt, was in the building. Yes, Brad Pitt showed up in a black SUV to wish his ex-wife, Friends star Jennifer Aniston, a happy 50th birthday. This is real.

So far, there are no details about what went on inside Jen’s bash, but here’s what we know for sure: Jen arrived looking amazing in a sexy black jumpsuit (even though she was going to look amazing no matter what because it’s her birthday party, and you look your most gorgeous at your birthday party, that’s just science), and Brad snuck in wearing his signature black jacket, newsboy cap, and long locks. It was previously reported that the former couple, who were married from 2000 to 2005, had reconnected after their recent respective divorces; Brad and Angelina Jolie announced their divorce in 2016, and Jen split from Justin Theroux in Feb. 2018. Those breakups inevitably led to rumors of a rekindling romance between Brad and Jen, and it was reported that Brad “wishes the best for her.”

Cut to Saturday night, and the possibility that Brad clapped and whistled as Jen blew out the candles on her birthday cake (you know he whistled!). Though Brad is currently in an “ongoing process to work through things regarding the kids” with Angelina Jolie — and was recently rumored to be romancing Charlize Theron — it’s pretty sweet that he showed up to support his ex on such a big night.
