There is love running through the veins of the cast of True Blood!

Hot on the heels of the news that TB stars Anna Paquin and Stephen Moyer are engaged, PerezHilton.com is reporting that Evan Rachel Wood and Alexander Skarsgard are hooking up.

A source on the set of Alex's new movie, Straw Dogs, says that Evan flew to Shreveport, La (where the movie is filming) to hang with her beau. Rumor has it they have been hooking up all along!

Let's hope these two get as lucky as Anna and Stephen or else is real blood could be drawn. It's such a sticky situation when you get romantic with a coworker and it doesn't work out. Ever been down that road? Do tell.

See more couples who hooked up on set!
