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 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.
