Is it the sexy stare? The haunted, tortured soul? What is it about bad boys that makes them so hot? For the ones on TV, I think their chiseled jawlines and perfectly sculpted torsos may also have something to do with it.

Here are my Top 5 Hottest TV Bad Boys:

1. Ian Somerhalder

He was hot on Lost, but Ian’s hotness has reached new levels now that he’s playing Paul Wesley’s evil, sarcastic vampire older brother on the new CW hit The Vampire Diaries. With his dark hair, light eyes, sexy smirk (and strange resemblance to Chace Crawford), the 30 year-old from Louisiana began modeling at age 10. Off screen he’s not so bad; he enjoys yoga, skiing and horseback riding. Sigh!

2. Sebastian Stan

Some people criticize Sebastian for looking kind of like a Chace Crawford/Penn Badgley hybrid, but I’m a big fan of the Romanian actor, who plays Serena’s mysterious beau Carter Baizen on Gossip Girl. He was also great on the show Kings, as the tortured, closeted prince who tried to cover up his true identity by partying and womanizing. The 26 year-old has been romantically linked to fellow GG co-star Leighton Meester. Sigh again.

3. Jeffrey Donovan

Okay, this one’s not so much a bad boy as he is a badASS. On USA’s Burn Notice, Jeffrey (who is 41? What??) plays lead Michael Westen, a kind of modern-day MacGuvyer who uses his spy skills to help regular people. Whether it’s detonating a bomb or driving in a high-speed car chase, Jeffrey’s constantly heating up the Miami coastline.

4. Josh Holloway

As soon as we heard Sawyer’s southern drawl on Lost, we could tell he was a kind of misguided cowboy up to no good. But with his golden tan, rockstar hair and crater-like dimples, how can we resist Josh Holloway? The 40 year-old was born in California but moved to Georgia when he was a baby, so he considers himself a “Blue Ridge Mountain boy.”

5. Stephen Moyer

This Brit’s about to turn 40 also, but that doesn’t keep him from seducing his co-star (and now fiance!) Anna Paquin as the 173 year-old vampire Bill Compton on HBO’s True Blood.  Stephen got his start in theatre, then hopped on the British tube before appearing in The Starter Wife and now TB. Anna is about to be a stepmom; Stephen has two children, a son named Billy and a daughter named Lilac.
