Former Spice girl Mel B's sex obsession is reportedly driving her friends and family away.

Mel B is said to have clashed with people closest to her due to her sometimes "raunchy" relationship with husband Stephen Belafonte, reports femalefirst.co.uk.

Her friend Victoria Beckham is also put off by the couple's behaviour as they talk about sex and are at it whenever they have a free moment.

"It can be uncomfortable to be around. Mel is just as up-front as her crude stereotype suggests. She seems to constantly talk about her sex life and ask you about yours," said an insider.

"Some people just can't handle being around her. Her and Victoria Beckham do not get on at all," the insider added.
