Jennifer Aniston threw a star-studded birthday bash for Justin Theroux on Saturday night (10 August).
The We're the Millers star (44) and her fiance were joined by 75 guests - including Ellen DeGeneres, Ben Stiller, Jimmy Kimmel, Tobey Maguire, Laura Dern, John Krasinski, Don Cheadle and Jason Bateman - for the lavish party at their $21-million Bel Air mansion in Los Angeles.
Kristen Bell, Isla Fisher, Samantha Ronson, Will Arnett, Malin Ackerman and Dax Shepard were also present to help Theroux celebrate his 42nd birthday - although Aniston's close pal Courteney Cox was noticeably absent.
A source told People that guests were treated to a drinks reception on the patio before going inside the newly renovated property to toast Theroux and enjoy a relaxed buffet, prepared by Aniston's personal chefs.
Rumours were flying that the couple were planning to tie the knot at the party - which also marked the one-year anniversary of their engagement - after they received a large delivery of sparkling wines and activated parking restrictions around their home. In addition, Aniston's personal hairstylist was spotted arriving at the property around noon.
However, Aniston insisted last week that she was in no hurry to wed.
She said: "We just want to do it when it's perfect, and we're not rushed, and no one is rushing from a job or rushing to a job. And, you know, we already feel married."
