Jennifer Aniston and Justin Theroux'Friends' star Jennifer Aniston and 'Your Highness' actor Justin Theroux had rumor mills buzzing after they two were spotted having an alleged dinner date in Los Angeles earlier this week.

The rumored couple were seen together at the Sunset Tower Hotel in L.A. and X17Online.com reported that a source told them the dinner date wasn't the first date for the couple, and that they have been on dates previously.

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

However, Celebuzz is reporting that Aniston's rep has told them that the story is false and said Aniston and Theroux were not dating, "What the story neglects to mention is the three additional people also at the dinner. It was a dinner with friends -- that's all."
