Jennifer Aniston and Justin Theroux hosted a star-studded engagement party on Sunday night at their Beverly Hills home.
"People were very causal, dressed casual and came with presents," a source told E! News.
"About 50 people came and some brought their kids."
Guests apparently arrived from 6pm, with Ellen DeGeneres, Portia DeRossi, Jennifer Meyer, Demi Moore, Ben Stiller and Tobey Maguire among the select group. No Brangelina though!
Jennifer and Justin met on the set of the film Wanderlust, and started dating around May 2011.
The pair got engaged back in August.
It will be the second time the 43-year-old walks down the aisle, following her high-profile first marriage to Brad Pitt in 2000, ending in divorce by 2005.
Judging by the casual nature of the engagement party, the pair's wedding plans are bound to be more down to earth than her $1 million wedding to Brad.
