Mariah Carey felt "extremely uncomfortable" when she was pushed to confirm she was pregnant during an appearance on the 'Ellen Degeneres Show'. The 'All I Want For Christmas is You' hitmaker - who has nine-year-old twins Moroccan and Monroe with her ex-husband Nick Cannon - appeared on Ellen Degeneres' talk show back in 2008, amid speculation at the time that she may have been expecting a baby.
