(Cover) - EN Showbiz - Jennifer Aniston reportedly enjoyed a romantic evening with actor Justin Theroux last night.

The 42-year-old star is believed to have been spotted having an intimate dinner with Justin at the Sunset Tower's Tower Bar in Hollywood. The pair met at the restaurant at 7pm and were seen laughing and joking as they ate, before leaving together at 10pm. It has been claimed Jennifer has been seeing Justin for some time, but doesn't want to rush into anything serious.

"Jen and Justin have recently started dating," a source told X17 Online. "They've known each other for a while, but they're more than friends now. They're cautious - they're both taking it slowly."

Jennifer was determined not to be photographed leaving the eatery with 39-year-old Justin, so the pair decided to exit from the underground parking lot. They left in a chauffeur driven car and both hid in the back so they didn't attract attention. It has been reported they were taken back to Jennifer's mansion in Beverly Hills.

The Tower Bar is said to be one of Jennifer's favourite venues as the low lighting gives diners more privacy.

Last month, it was reported Jennifer had found a new boyfriend who is a "homebody" and the pair have been enjoying low-key dates watching television and sharing a bottle of wine. (C) Cover Media
