Who Went to Jennifer Aniston’s Christmas Party?

Jennifer Aniston, she of the perfect hair and bubbly personality, has a Christmas tradition of a tree-trimming party, which she hosts each year at her home in Bel Air, Calif. for her family and close friends. So, who showed up to this year’s holiday festivities? Well, one person in particular might come as a bit of a surprise.

None other than Gwyneth Paltrow and her husband Chris Martin were photographed arriving to the holiday fête on Saturday night!

Gwynnie and Jen, both exes of Brad Pitt have never starred in a film together (at least we don’t think they have?) nor have they ever been pictured together (again, as far as google.com knows), so this is the first we’re hearing of their friendship. Perhaps they’ve bonded over their shared dislike for Graydon Carter’s Vanity FairWhile Gwyneth successfully put the kibosh on an allegedly explosive exposé about the GOOP-y glamazon, set to appear in an upcoming issue of the mag, it’s unclear exactly which of her celeb friends stepped forward to help the actress get the piece scrapped.

In any case, Jen’s party was super star-studded as Robert Downey Jr., Courteney Cox (possibly with her new beau?), Chelsea Handler and Will Arnett were also among the guests snapped arriving to Jen’s shindig. Launch the gallery above to see the (full-disclosure) grainy shots.
