X17 EXCLUSIVE - It's Official! Jennifer Aniston And Justin Theroux Go Public With Their Romance



Jennifer Aniston and Justin Theroux went public with their relationship Thursday night with another date at Jen's favorite restaurant - The Tower Bar at Sunset Towers.

X17online was the first to report the relationship two weeks ago when we spotted them on a romantic evening at the same place! Since then, the two have been almost inseparable -- spending lots of time together at Aniston's Beverly Hills mansion.

Thursday night, the pair arrived separately, just as they did last time. They kicked off the evening early -- at 7:30 -- and stayed for almost three hours!

And when it came time to leave, Jen had a car waiting for her in the underground parking garage AND one waiting in front of the building so should COULD have chosen to leave under cover and not be photographed ... but Aniston walked right out the front door with Justin, with a big smile on her face.

Our photographer on the scene tells us, "They weren't even hiding anymore. She knew we'd spot her together with Justin but she still left with him in the same car. Coming from her, that's as good as a press release announcing she has a new boyfriend!"

Jenstin? Aniroux? J&J? Whatever you call it -- Jennifer and Justin are ON!
