We always knew the camera loved Jennifer Lopez, but it turns out J.Lo owes her posing skills to more than good genes. The star tells InStyle this month, "When I was maybe 15 or 16, I took a class at a modeling agency." That could explain the awesome modeling skillz.

"But mostly," Lopez adds, "I think my ability [to photograph well] is innate. And it’s funny because I see that my daughter, Emme, has it too -- that something special. She knows how to play for the camera.”

She sure has had enough practice with dozens of magazine shoots on her resume (just this year she landed covers for Vogue, V, Glamour France, Good Housekeeping South America and now the September issue of InStyle). But getting her start with a modeling class, before she jumped to Hollywood, probably wasn't a bad idea -- in fact dozens of actors and actresses have started that way.

Ashton Kutcher famously got his start after winning the Fresh Faces of Iowa modeling contest, bringing those flats abs to high fashion runways and Abercrombie & Fitch alike. Cameron Diaz signed with Elite Model Management at 16, scoring the cover of Seventeen long before she was a household name. Everyone's favorite vampire, Rob Pattinson, also took a stab at modeling at age 12... but started losing jobs when he got too "manly." [Ed. note: the modeling world's loss was very much our gain.]

Who else, like Jennifer Lopez, dipped their toes into modeling before hitting the big (and small) screen? See a few of fave models-turned-actors below.
