Robert Pattinson and Kristen Stewart got close at a gig this week - just days after the Hollywood hunk confirmed they are dating.

The couple - who play Edward Cullen and Bella Swan in the 'Twilight' films - were seen getting cosy at the Halfmoon pub in Putney, South London, while watching Robert's younger sister Lizzy perform.

An onlooker said: "They were very low-key. You would not have guessed they were one of the most famous couples in the world."

 The 23-year-old screen hunk's sibling was supporting Starsailor frontman James Walsh at the 300-capacity venue.

'Good Souls' singer James was thrilled to have had two of Hollywood hottest young stars watch him perform.

The 29-year-old musician said: "Robert and Kristen were there to support Lizzy as she took the stage. I was very flattered to learn they stuck around for my set too."

Robert and Kristen - who have reportedly been staying at a London hotel together since last Saturday (20.02.10) - were also spotted kissing in a bar earlier this week after the 19-year-old actress attended the Burberry Prorsum catwalk show, which was part of London Fashion Week.

British councillor Nicholas Clark posted on Twitter: "In Marquis of Granby with Robert Pattinson and Kristen Stewart! A couple of kisses - left in separate cars."

After months of speculation, Robert confirmed the couple's long-rumoured romance at a post-BAFTA Awards dinner on Sunday night (21.02.10).

He said: "It is extremely difficult but we are together, yes. We can't arrive at the same time because of the fans, it goes crazy."
