But it's time to call attention to a fresh crop of forbidden baddies getting viewers' blood pumping:
Ian Somerhalder as Damon
The 30-year-old star, best known for his role as Boone on ABC's Lost, brings some bloodsucking action to network TV on the CW's new series, The Vampire Diaries – out this fall. As smug vampire Damon, Somerhalder gets in between his younger vampire brother Stefan and his mortal teen crush Elena.
Kellan Lutz as Emmett
Playing ripped big brother Emmett to Pattinson's Edward Cullen can't be the easiest job, but Lutz – who also stars on 90210 – has his own set of "Twilighters" screaming. The 24-year-old hunk, who landed on PEOPLE's "Hottest Bachelors" list, has girls (and their moms!) ogling over his steamy shirtless shots.
Alexander Skarsgard as Eric
As Eric Northman, the brooding vampire "sheriff" presiding over Bill Compton's Louisiana area, Skarsgard, 32, brings a commanding presence to HBO's cult hit True Blood. The blond Swede's character also owns hotspot Fangtasia.
So which vampire hottie do you want to be bitten by?
