Joined by a star-studded list of friends including Ben Stiller, Isla Fisher, Sacha Baron Cohen, Dax Shepard, actress Jennifer Aniston hosted a memorable 42nd birthday bash for fiance Justin Theroux at their Bel Air mansion.
Aniston, 44, chatted with her female colleagues whereas the birthday boy, who received gifts from Cartier and Barney's, spent a majority of the night with Shepard and Jimmy Kimmel, reported Us magazine.
"Several of Justin's friends spent the afternoon at the house hanging out by the pool with him and celebrating his birthday.
"It was a relaxed afternoon and they were all in the cabana area having drinks and listening to music like Kanye West and The Kinks," a source said.
With a catering team preparing an outdoor barbecue buffet, Aniston and her fiance began to greet the rest of their guests around 7pm, with the pair "making a point to hug everyone that arrived."
The birthday celebration also marked the one-year anniversary of the couple's engagement.
