Mel B "paranoid" her husband will run off with someone else

Spice Girls star Mel B is "paranoid and insecure" about husband Stephen Belafonte "running off with another girl".

The singer - who is currently in the middle of a reunion world tour with the girl band, reportedly gets "incredibly jealous" when the movie producer is around other women, and keeps him "in her sights" when they go out together.

A source told Britain's Closer magazine: "Mel gets incredibly jealous. She is very insecure and paranoid about Stephen running off with another girl. She has to keep him in her sights whenever she goes out."

Despite Mel's insecurities, it has been claimed the couple are planning a second wedding for April, after upsetting her family with their 'quickie' marriage in June last year.

A source said: "It's going to be a huge celebrity wedding. She wants all of her and Stephen's family to be there to make amends for them not being able to be present last time."

Mel's previous relationship with Hollywood star Eddie Murphy ended in December 2006 while she was five-months pregnant with his baby.

Shortly after the split Eddie revealed he was dating film producer Tracey Edmonds.

Mel has an eight-year-old daughter, Phoenix Chi, from her first marriage to Dutch dancer Jimmy Gulzar, and nine-month old daughter Angel Iris from her relationship with Murphy.
