The hot but pregnant Jessica Alba might be a one-man gal now, since she got engaged to producer Cash Warren, but according to a new book of essays, the 26-year-old actress admits that she was once labeled "a slut."

According to People magazine, Alba remembers being labeled "a sixth-grade slut" by her elementary school principal and a couple of "self-righteouse PTA moms."

"The accusation still ricochets," said Alba. "They think I'm a slut?"

In If I'd Known Then, a book due out this spring, Alba reveals that she first kissed a boy when she was 7 years old "so he would pick [her] for the neighborhood baseball team."

"Boys are awful," Alba writes. "They are made of nothing but hormones until they're about 20 or 21. It's fun to have a crush, but don't think it's forever."

Alba's essay joins other essays written by soccer player Julia Foudy, activist Zainab Salbi and actress Danica McKeller, according to People.
