Bieber can't babysit Mariah's twins

Justin Bieber won't be allowed to babysit Mariah Carey's twins.

The 'Baby' singer hit it off with the 41-year-old songstress when they filmed a video for their duet of Mariah's single 'All I Want for Christmas Is You' recently, but despite their friendship Mariah's husband Nick Cannon has no plans to let the 17-year-old popstar care for their seven-month-old babies Moroccan and Monroe.

He said: 'Justin didn't meet our kids because Mariah didn't bring them to the set of the video. I think he will eventually but hell no (would I ever let him baby-sit)!'

Nick recently revealed his spouse is in her element planning the babies' first Christmas and the family will spend the holiday season in the exclusive ski resort of Apsen, Colorado where they will 'be as festive as we can.'

He added: 'I think my wife has been planning this all her life, Christmas with the kids. We always have a real Santa Claus come with real reindeer on Christmas Eve, but this is the first time with our own children.'
