In case you haven't heard, Kate Bosworth really needs to eat.
For a long time, however, this Janet Jackson had the opposite problem. Michael's sister gained approximately 60 pounds awhile back, an amount that still shocks the singer.
"I could not believe how big I was, how heavy I really was," Jackson, 40, told Extra. "I would see myself in the mirror, but I wouldn't look too often. I didn't want to get used to that image."
Jackson lost the weight through healthy eating and tough workouts â€" and she's offended by speculation that she went all Ashlee Simpson on her fans; i.e. had plastic surgery.
"It does drive me crazy," she says, "because I've worked real hard â€¦ and I think it's really easy for (the tabloids) to write it off as (surgery)."
She jokes, "It isn't hurtful â€" it just pisses me off. â€¦ I want to kick some ass."
Based on how she looks now - check out this Janet Jackson picture - we're pretty sure she could do just that to anyone out there.
Jackson does admits she had some cosmetic work done when she was a teen.
"It's no secret," she reveals. "When I was 16 I changed my nose. Would I do it again? I don't know. â€¦ I've seen a lot of women that have been pulled and snatched, and it's not too cute."
Ok, but let's get to the important stuff: Will Janet now follow in the rumored footsteps of Beyonce and get married? She's been dating producer Jermaine Dupri for years.
"I don't know," she says. "If that's God's will, then it will happen."
She'd have children with Dupri, she says: "I would love to â€¦ with him. Never thought I would. God willing, it will happen."
