Actress Michelle Trachtenberg was freaked out by the creepy "Buffy The Vampire Slayer" fans who staged an online countdown to her 18th birthday - when she became legal for sex.

The star was 14 when she landed the role of Dawn Summers on the cult show and she immediately won the affection of fans - but some took it too far.

She explains, "Even at the time, I was like, 'You're never gonna get a chance (to have sex with me)! So what's your counter for?'

"If anyone's checking a counter, it's pretty safe to say that I'm not going to give them much thought. It's creepy."

Trachtenberg admits she once dated a guy who was obsessed with her impressive acting resume.

She tells Complex magazine, "I once dated a guy who was like, 'Holy s--t, I just made out with Harriet The Spy!' That's messed up. Don't say that. I was 10, you're 30, it's just weird."
