Janet Jackson gets lapdance from Jermaine Dupri

Janet Jackson and her boyfriend Jermaine Dupri reportedly shocked party goers due to their saucy display at the fifth anniversary bash for US magazine In Touch last Wednesday.

According to Britain's The Sun newspaper, a party goer at the exclusive New York bar Tenjune said: "They were all over each other and Janet was thrilled when Jermaine decided to treat her to a private dance."

Despite having a very close relationship, Janet recently revealed she doesn't want to marry Dupri, she said: “I didn’t really take anything from my personal marriages,” Jackson said of her role. “But from experience, and even from doing this film, it makes me realize that marriage is definitely a work in progress … But if it’s something you really want and the love is there, you will put in the work in time.”

Jackson married James DeBarge in 1984 and annulled the marriage 1985 - she then ied the knot with Rene Elizondo in 1991, which ended in divorce in 2000. “He’s never been married,” she said of Dupri, 35.

When People.com asked Dupri if he thought his relationship with Jackson was successful - he said:  “The altar is like a party for your marriage. That is how I look at it.”
