FORMER America’s Got Talent judge Howard Stern has hit back at suggestions Simon Cowell helped rescue Mel B from her toxic marriage to Stephen Belafonte.

He ranted: “He jumped in and fought off her husband? I bet, a real man.

"He should jump off a cliff, f***ing maniac, that guy is such a f***ing douche bag.

“He’s no knight in shining armour unless you’re a hot chick and you’re in a marriage that I guess you want to get out of, and then he might jump in.

Mel, 41, who worked with Howard for three years on the show, filed for divorce from Stephen, 41, last month and has since claimed he was abusive towards her over their decade-long marriage.
