How Taylor Swift, Ryan Gosling & Jennifer Aniston Celebrate the Holidays
Justin Theroux helped fiancé Jennifer Aniston carry on a favorite Christmas tradition this month by co-hosting the star's annual tree-trimming party. Famous pals - including Demi Moore, Ellen DeGeneres, Ben Stiller, Tobey Maguire and Portia de Rossi - were among those that took part in the holiday fun at the couple's Beverly Hills home. The thought of hosting such a star-studded gathering may be daunting to some, but Aniston remains unrattled by end-of-year pressures. "I love the holidays," she says. It's not a stressful time for me at all."
