Robert Pattinson and Kristen Stewart have been spotted leaving a concert together (and having a romantic dinner together) in Los Angeles. Seems like the romance is on.

Pattinson is currently filming 'Water For Elephants' in California but he obviously took some time out to spend an evening with his rumored girlfriend, Kristen Stewart.

The pair seemed keen to leave the Sam Bradley concert unobserved via the back door and made sure they were not photographed holding hands. They then left quickly in the back of a car.

Earlier, according to E! Online, the rumored couple also grabbed a dinner together at Pattinson's favorite West Hollywood place, SoHo House.

An onlooker told the site that Pattinson and Stewart sneaked into the restaurant unnoticed through a private underground entrance.

The source said that Pattinson and Stewart seemed 'very happy' together.
