Former Backstreet Boy Nick Carter claims he lost his virginity to Debra LaFave. LeFave, if you remember, was the infamous blonde teacher from Florida, who got busted for sleeping with her students.

The former Backstreet Boy told Howard Stern on Sirius Satellite Radio yesterday that he dated Debbie LaFave, 23, for 18 months when they were classmates, and busted up with her when he learned from pals “she had cheated on me with a girl.”

“And then, before you know it, a month or two goes by and it’s back to the old nose up in the air and who are you?” Of all the women he’s slept with, LeFave was “probably No. 1. But maybe that’s just because it was my first. Actually a lot of the girls I’ve just had the best sex with or best anything with have been just normal girls.”
