"X Factor" UK judge, Mel B allegedly has a weird obsession for sex and this has placed some of her relationships with friends and partners in jeopardy.

A source close to the singer dished to Female First and confirmed that Mel B's obsession with sex started when she was dating Stephen Belafonte, who is now her husband.

The source revealed that the couple would have sex all the time as long as they were not doing anything and that their conversations would always involve topics about sex, according to Web Pro News.

At some point, Mel B and Belafonte would even go out of their way to ask couples about their personal stories about sex, which somehow made them feel uncomfortable.

"It can be uncomfortable to be around. Mel is just as upfront as her crude stereotype suggests. She seems to constantly talk about her sex life and ask you about yours. Some people just can't handle being around her. Her and Victoria Beckham do not get along at all," the source said.

Mel B and Victoria both belong to the popular '90s girl group Spice Girls but despite of their success, the group only lasted for a few years, Times of India noted.

No one knew the real reason for the group's split but Mel B recently dished that it was her co-member Geri Halliwell who initiated the breakup.

In a recent interview on "Larry King Now," Mel B explained, "I think I'll always be Scary Spice. I still am very loud sometimes and a bit opinionated."

The 39-year-old revealed a time when she and other members of Spice Girls would fight like they were dogs and cats, eventually leading to their official split in the year 2000, according to ABC News.

"When Geri left the group, it was bad. She left on my birthday and didn't tell anybody. She just didn't show up. We had the rest of the tour, the American part of the tour to continue," she explained.

When asked if there was ever bitterness between her and Geri, Mel B admitted that for a time there definitely was.
