The Emmy nominee, who has proven he has the abs of a man half his age, was toasted by dozens of friends at a party thrown by tequila company Casamigos Monday in Beverly Hills.
The Jury Duty star shared snaps and video from the festivities on his Instagram Stories, revealing that the centerpiece of the celebrations was a cake with a black and white photo from his modeling days.
The flashback snap featured a shirtless James with gold ‘5’ and ‘0’ candles at the top of the photo and the words ‘Happy Birthday James’ beneath.
The party was held at the Sheats-Goldstein residence which has been featured in multiple music videos, including Doja Cat‘s Say So, and in Nelly’s The Fix.
Famous friends including Westworld co-stars Ben Barnes and Aaron Paul, as well as Shock and Awe pal Woody Harrelson as well as Jury Duty co-star Ronald Gladden were there to toast his good health.
Aaron Paul was seen holding the personalized mug with a collage of James’ face on it made by Westworld star Tessa Thompson.
James kept his look comfortable for the big day, stepping out in basic black.
The Dead to Me actor looked dapper in a black suit and shoes with a black T-shirt as he posed for a photo thanking Casamigos and the company’s global VP Rachel Zalis for the party.
‘A huge thanks to @casamigos and @rachelzalis for keeping the party going strong and the drinks flowing late!’ the guest of honor wrote on a photo from the big night.
