Alexander Skarsgard, Kate Bosworth split

"True Blood" star Alexander Skarsgard and actress Kate Bosworth, who have been quietly dating for the past two years, are apparently done-zo. According to Us Weekly, the couple broke up recently, leaving Skarsgard free to flirt at last weekend's (July 23-24) Comic-Con parties.

"It was very mutual," a source tells Us Weekly. "And it happened a while ago."

Skarsgard, 34, who plays vampire Eric Northman on the popular HBO show, was once rumored to be cozying up to "True Blood" co-star Evan Rachel Wood. Bosworth, 28, previously dated Orlando Bloom.
