JANET ON THREESOMES ('IT'S COOL') , MARRIAGE ALLERGIES & WHY SHE ISN'T MATURE ENOUGH TO BECOME A MOTHER.

Janet Jackson is in no rush to wed longterm boyfriend of 6 years, Jermaine Dupri, because she thinks she is "allergic to marriage". The sexy singer admits she has been put off the idea after two failed unions - her first marriage to James DeBarge broke down in 1985 after one year, and the second, to Rene Elizondo, ended in divorce in 1999 after 13 years together. But the 41-year-old beauty, who has been dogged by engagement rumors in recent months, insists she isn't ruling out a wedding to music mogul Dupri completely. She says, "If it's (meant) to happen, it'll happen. I like where we are, and I'm happy where I am. I've done it twice before. I'm afraid I might be a jinx. I might be allergic to marriage." And although Jackson may feel she's allergic to marriage, there's one thing the first-time NAACP Image Award winner isn't afraid to admitting is cool. Threesomes. Since her new album Discipline is about the experience of having sex with multiple partners, when Janet was asked if she was into threesomes she replied, "I think whatever you're into, as long as you both are into it, it's cool."

In related news, the star, who has been the subject of a never-ending rumor suggesting she gave birth to a daughter with her first husband, De Barge, says she's fed up with family and friends' attempts to persuade her to have a baby - because she isn't ready to become a mother. Jackson claims she eventually wants to start a family with Dupri, but isn't convinced she is mature enough to raise a child. She says, "I just have to hurry up. I get so much pressure from people I don't even know and I think, 'My God, am I missing my moment?' Even my mother mentioned something to me the other day. But now you can have your eggs frozen and there are all sorts of things you can do. I've still got time so I think I'm okay. I've got to get a little more kid out of me first before I move on and be childish with my child."

AFTER THE JUMP, FIND OUT WHY JANET HAS MADE A VOW TO STOP DISCUSSING HER BROTHER, MICHAEL IN ANY FUTURE INTERVIEWS.

Janet has vowed to stop talking about her brother Michael - because she is fed up with answering questions about his headline-grabbing lifestyle. The youngest child of Katherine and Joe Jackson's clan was just a toddler when her brother found fame with The Jackson Five refuses to discuss her infamous sibling in a desperate bid to establish herself as an artist independent to the Thriller hitmaker. She says, "I'm just done talking about my brother. I'm not going to answer questions for him. I've done it all my career."

However, before Janet made her vow, she cast doubt on her Michael's participation in a planned Jackson 5 comeback tour, because she doesn't know if he's ready to go back to singing in a group. Elder brother Jermaine Jackson has voiced plans for the ABC hitmakers to embark on a reunion tour later this year (2008), complete with the Thriller superstar - but Janet isn't convinced. She says, "I know it's been kind of tough for Mike. Maybe he just wants to continue to be a solo artist and if that's what he wants, you have to respect his wishes. But what an impact it (a reunion) would have on the world. (I'd) be the first in line to buy a ticket."
