Jennifer Aniston, Justin Theroux Buy 10 Foot Christmas Tree For Beverly Hills Home

Jennifer Aniston and fiance Justin Theroux are getting ready for the holidays but bringing some Christmas spirit to the massive Beverly Hills mansion they share.

The betrothed coupled bought an enormous 10 foot Christmas tree — a noble fir premium tree, to be exact — over the weekend at the Beverly Hills Christmas tree outlet Mr. Greentrees, according to a report from Us Weekly.

"She likes [her trees] really full and fluffy," a worker at the store told the magazine.

Aniston and Theroux brought the tree home just in time for a star studded party they threw at their house over the weekend. Though it was originally reported to be an engagement party, the celebration was actually Aniston's annual tree trimming extravaganza, which she holds close to Christmas every year.

Some of the high-profile attendees included Ellen DeGeneres and wife Portia de Rossi, Ben Stiller, Demi Moore, Tobey Maguire and wife Jennifer Meyer, actress Lake Bell and Aniston's long time agent Kevin Huvane.

Though this weekend's part did not in fact celebrate the couple's engagement, that doesn't mean they haven't been hard at work with wedding plans. According to a new report, Theroux is helping Aniston design her wedding gown for the big day and has attended several meetings with designers to iron out what look Aniston wants for her nuptials.

"Jen always consults Justin on her wardrobe, whether it's casual or if she's trying to pick a red carpet dress," said a source close to the couple. "She really values Justin's opinion and says he's often the only one to be brutally honest. They met with Valentino's creative directors Maria Grazia Chiuri and Pier Paolo Piccioli to discuss wedding dress designs and Justin had a big input. They showed Jen a variety of fabrics and Justin helped them recreate what he knew was in Jen's head."
