Robert Pattinson was outbid at a charity auction on Thursday night (13.11.14).

The 'Rover' star, who is dating 'Two Weeks' hitmaker FKA twigs, attempted to secure a lot offering dinner for 12 at Gjelina restaurant in Venice Beach, California for $6,000 at the 7th annual Go Go Gala at the Montage Hotel in Beverly Hills, but was forced to go home empty handed after another guest bid $8,500.

The 28-year-old actor, who is close friend's with the Go Campaign's founder Scott Fifer, did not publicly bid on any other items, but a source said he privately contributed a ''significant amount'' to the organisation, which aims to improve the lives of orphans and vulnerable children around the world, and seemed to have a great time.

The insider told E! News: ''He wasn't being bothered by anyone and seemed to be enjoying himself before the dinner began, and, even though there were young girls present, he was not approached by any Twi-hards!''

Robert was dateless for the evening, but was spotted chatting to 'Always Sunny in Philadelphia' star Glenn Howerton before the gala kicked off.

The source said: ''He looked upbeat and was constantly running his fingers through that shaggy new 'do before he headed into the ballroom a few minutes early for dinner.''

The British star also attended the event last year and donated a meet-and-greet on the set of 'Twilight: Breaking Dawn' for the non-profit's online auction two years ago, which raised $80,000 and led to the creation of the Program Advancing Girls' Education (PAGE) in Cambodia.
