Janet Jackson Drops New Album, 60 Pounds

Inside, she's just "20 Years Old" -- and she looks it too!

Janet Jackson is going public with her newly svelte body on "Entertainment Tonight" after gaining weight for a movie role that never materialized with producer Lee Daniels ("Monster's Ball"). With her new single "Call On Me" out June 19, Jackson had to get in shape fast -- and so she did!

"I have to give credit to my parents' genes, I suppose," said Jackson, who also credits good nutrition and a personal trainer with her weight loss over the last six months. In the mean time, she speculates Mariah Carey will get the waitress role she was going for -- and that's okay, because she's in love with her new album.

"I love this, so hopefully everyone else will enjoy it," said Jackson to ET. "It's different, it's a little reminiscent, yet it's new and fresh."
