Are Alexander Skarsgard and Kate Bosworth a Couple?

True Blood hottie Alexander Skarsgard and his Straw Dogs co-star Kate Bosworth both attended the GQ “Men Of The Year” party held at Hollywood’s Chateau Marmont last night.

Alex has denied that he’s currently dating anyone, though this past summer he was rumored to have been seeing his True Blood co-star Evan Rachel Wood, who plays the Queen of Louisiana in the HBO series.

Alex and Kate, however, were spotted at the GQ event last night holding hands and placing their hands on the smalls of each others’ backs, and onlookers said they were looking quite comfortable together. Kate presented Alex with the award for Best Villain at the Scream Awards last month (pictured above).

Straw Dogs, currently in post-production, is about an L.A. screenwriter who relocates with his wife to her hometown in the deep South. While tensions build between them, a brewing conflict with locals becomes a threat to them both. It co-stars James Marsden and James Woods and is slated for a 2011 release.
