Robert Pattinson has a night out with Disturbia actress Sarah Roemer.

The actor is in a relationship with his Twilight co-star Kristen Stewart.

However, Robert still enjoys spending time with his female friends and was spotted out with Sarah on Saturday night.

The pair joined more friends for dinner at LA eatery La Poubelle before heading out for drinks at the Soho House.

The 25-year-old was typically dressed down in a scruffy plaid shirt and baseball cap, but he was still attracting plenty of female attention.

"Rob was literally fending off advances from girls, left and right," an onlooker told X17Online.com. "Every female in the bar wanted to get close to him and for the most part, he politely ignored them."

At the end of the night the star tried to keep his head down as he left the bar and hopped into a car in which 27-year-old Sarah was waiting.

Earlier this year Kristen confirmed that she and Robert were dating after rumours had been circulating since 2008 when filming on the Twilight saga began.

However, the star also confirmed that she would never speak openly about her love life.

"I don't worry about it at all. It's just one of those things. I'm selfish. I'm like, "That's mine!" And I like to keep whatever is mine remaining that way," she said in an interview with GQ.

"It's a funny little game to play and it's a slippery slope. I always say to myself I'm never going to give anything away because there's never any point or benefit for me."
