Jennifer Anniston and her fiancé Justin Theroux held their annual holiday party in their Bel Air home Sunday, Dec. 8. The event drew a large number of well-known stars like Courteney Cox, Robert Downey Jr., Jason Bateman, Tobey Maguire, Chelsea Handler, and many more of equal fame.

E! News was told by an anonymous source that the party began at 6:30 Sunday evening. The source also reported that at least 50 guests showed up and said, "The party was held outside on a cold night. Everyone was bundled up in jackets and scarves to stay warm."

Anniston’s home was decorated beautifully. The trees on her property were decorated white lights, as was the roof of the house. The care that went into the Christmas decorations left no question of Anniston’s fondness for the holiday.

Us Magazine was more interested in the attendance of the fellow Brad Pitt ex, Gwyneth Paltrow. Paltrow and her husband, Coldplay’s lead singer, were photographed driving to the party.

The party only lasted a couple of hours but the evening was undoubtedly a memorable one for the partygoers.
