UPDATE: It was first reported that Jennifer Aniston and Justin Theroux threw an engagement bash, but a source tells GossipCop the couple actually invited friends over for a "holiday party."
The original story continues below:
According to X17online.com, the couple, who are set to wed in the near future (at least we hope they are!), threw the low-key bash, which was attended by a handful of celebrities including Tobey Maguire and Jennifer Meyer, Demi Moore, Ellen DeGeneres and Portia De Rossi, Ben Stiller and Lake Bell.
The vibe of the party was relaxed, with guests dressing down in jeans and casual shirts as they came bearing gifts for the happy bride and groom-to-be at around 7 p.m. A DJ played alternative music while the pair enjoyed their company inside as the rain poured down.
