Jennifer Aniston Celebrates "Wonderful" Life & Throws Star-Studded Xmas Bash

Jennifer Aniston has celebrated the festive season by throwing another major Hollywood Christmas party, cramming her estate to the rafters with A-list stars and friends old and new. Co-hosting with her fiancé Justin Theroux, Jennifer made sure as many big Hollywood names as possible were in attendance, drawing an enviable roster of guests that included Robert Downey Jr., Chelsea Handler, Courtney Cox, Gwyneth Paltrow, Chris Martin, Tobey Maguire, Jason Bateman and Will Arnett.

Jennifer Aniston Sure Knows How To Rock A Party.

A seasoned party-thrower and goer, Jennifer told Parade magazine her tried and tested hosting tips to make any festive bash a success. "There's usually three different kinds of chili at the tree-trimming party. There's a vegetarian chili, a turkey chili and a good ol' beef chili," the actress said. "I can't honestly say I make that, but I do make some Rice Krispies treats and hot chocolate. My best hostess tip is to have good food and really good music! We usually put on the Charlie Brown Christmas album. That's my favorite. And then we'll go to Bing Crosby and stuff like that."

Perhaps Being With Justin Has Helped Jen Leave Her "Awkward" Times Behind.

It could be said that the party celebrated the fact that Jennifer Aniston is finally comfortable in her own skin. So comfortable it seems that she can invite Gwyneth Paltrow, the ex of her ex-husband Brad Pitt, to a glamorous Christmas party without so much as a stab of anxiety.

The gossip media is constantly flooded with speculation regarding Jen's official wedding date or whether the couple have finally decided to turn two into three. Despite the constant obsession with her lovelife, Jennifer revealed that her most "awkward" days are far behind her. "[At the moment] There's nothing to worry about," the 45 year-old star said, admitting "although I don't think I had a care in the world at 25, either. That all started in my 30s, my awkward phase. ... But it doesn't matter to me because it just gets better. ... I'm more in my body; I'm more in my mind. Life is full. Life is wonderful. We're very, very fortunate."

Seemingly, Jen can only finally look back on her past relationships and former love rivals with wisdom because she's so happy and comfortable with Justin. "My life is so fantastic," she revealed. "I'm so happy. There are a lot of exciting things that I'm excited about doing. We're about to do a sequel to 'Horrible Bosses,' which is such a fun character for me. And I think I'm going to try at some point next year to direct a full-length feature, which I'm extremely excited about. I'm just so happy and I'm grateful for my fans."

Take it from Jen though - happiness doesn't always come naturally. She revealed her mantra-like advice to Jason Sudeikis for Glamour: "Go to therapy. Clean up all of the sh*t. Clean up all of the toxins and the noise. Understand who you are. Educate yourself on the self ... [But] you can undo a lot of things. If you're not happy, you can become happy. Happiness is a choice."
