Nick Cannon and Christina Milian have put their differences behind them to reconcile live on his radio show.

The pair were one of the urban world's hottest couples before they split in 2005 following reports of cheating on Nick's side.

Both have moved on since with Christina becoming mother to two-year-old Violet and Nick happily married to Mariah Carey and father to twins Morrocan and Monroe.

While Christina called in to promote her new role on The Voice, the conversation soon turned to their failed relationship. "Regardless of my big mouth back in the day, I’ve got all great things to say about Nick too," Christina admitted.

Nick's co-host Sarah Lee forced Nick to apologise for his womanising ways, saying: "I’m sorry for the things that I did. We was young."
