NICK WANTS MARIAH BACK!

ONE-MAN baby factory Nick Cannon, 41, says the love of his life is the one that got away — his ex-wife, Mariah Carey! Now he wishes they could reunite!

Nick — who co-parents 11-year-old twins Moroccan and Monroe with Mariah, 53, and has fathered eight children with five women, with another baby on the way — admits he’d go back to the songbird in a heartbeat if things “could be like they were.”
