Jennifer Aniston Justin Theroux 26th American Cinematheque
It May Be Winter But It's All Pretty Sunshiney For Jennifer Right Now.

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."
