An eyewitness told Us Magazine that several of Theroux's pals spent the afternoon by the house's pool with him.
The insider said that it was a relaxed afternoon and the guests were all seated in the cabana area, while having drinks and listening to Kanye West and 'The Kinks' tracks.
The catering team at the party prepared an outdoor barbecue buffet, when the pair began to greet the rest of their guests at around 7pm and made a point to hug everyone that arrived.
While the actress chatted with her gal pals, Isla Fisher and Jen Meyer, the birthday boy, who received gifts from Cartier and Barney's, spent a majority of the night with Shepard and Kimmel.
Hollywood celebs like Kirsten Bell, Dax Shepard, Jason Bateman, Tobey Maguire and many more attended the birthday bash.
