Anna Paquin, Stephen Moyer, Alexander Skarsgard and the stars of True Blood hit the Arclight Hollywood theater Tuesday night for a screening of the season four premiere of the show.

Skarsgard looked hot as usual (see our gallery below,) but the hotter news was Amanda Seyfried! She isn't on the show, but attended the afterparty and was spotted leaving with a mystery man!

Seyfried, who is newly single from Ryan Philippe after eight months of dating, grabbed a meal with ex Dominic Cooper only this past weekend. Enjoy being a single lady, Amanda!

Check out Amanda and the guy in our video below, and see video of all the stars of True Blood at the premiere after the jump!
