Mariah Carey’s wedding to Nick Cannon was not a last minute thing according to Oprah Winfrey – the singer has her married name tattooed on her back when she appeared on the chatshow before tying the knot.

Tom Cruise’s new best pal admitted she regrets not questioning the E=MC2 singer about her relationship to Cannon when she appeared on the show on 14 April.

Despite being introduced to her then-fiance backstage, Oprah thought nothing of the magical moment, or the suspicious tattoo etched on Mariah’s back.

She said: "She'd done the tattoo on her back that said `Mrs. Cannon,' so they were already planning on doing it (getting married)."
