Jennifer Aniston Wanderlust LA Premiere Pictures

Jennifer Aniston and her boyfriend Justin Theroux were both in attendance at their LA premiere of Wanderlust at Mann's Theatre on Thursday evening, though she decided to pose solo to kick things off. Jennifer, who celebrated her 43rd birthday with a private party at the Chateau Marmont last weekend, mixed up her standard little black dress habit with this sexy strapless black and white Tom Ford number. Justin was looking sharp in his suit, but he skipped most of the arrivals line and let Jennifer have the spotlight. Instead, Jennifer was focused on her leading man in the film, Paul Rudd. Aniston showed off her abs in a bra for a sexy GQ cover shoot with Paul, while Justin spoke about their actual romantic relationship calling it "happy" in an interview.

Wanderlust hits theaters on Feb 24, so we should be seeing a lot more of Jennifer, Paul, and Justin over the next week. Jennifer, for one, will also be honored with a star on the Hollywood Walk of Fame with a big ceremony next Tuesday.
