Janet Jackson

Will Janet Jackson ever stop posing for sexy photos? "Of course. When I'm 80," she tells Vibe. "That's when I'll call it quits." The 40-year-old R&B singer appears on the cover of Vibe magazine wearing a skimpy bikini bottom, a necklace made of shells, and her right arm over her breasts.

Two years ago, Justin Timberlake pulled off a part of Jackson's custom, briefly exposing one of her breasts, during the Super Bowl halftime show. In an interview in the magazine's September issue, on newsstands Aug. 15, Jackson says the incident is history.

"It's just over and done with. It's old. It's the past. It's history. I'm onto something new. Everybody got their licks in - those who wanted to - and it's done," she says.

Jackson credits her boyfriend, 33-year-old music producer Jermaine Dupri, for giving her self-esteem "a little boost."

"I came to realize that younger men had less of a problem with who I am than older men," she says. "With the younger guys, there was less ego. Things were less competitive. They weren't threatened by who made more and who made less."

She says that with Dupri, she feels as if she's met her match.

"When I look at Jermaine, I see myself," Jackson says. "I feel as if I'm looking in the mirror. The connection I feel with him I have never felt with anybody else."

Her new album, "20 Y.O.," is slated for release Sept. 26, with production from Dupri and longtime collaborators Jimmy Jam and Terry Lewis.
