Nicola and her new boyfriend, Charlie Fennell, (who has been compared to boxer Ricky Hatton - though we're not sure if that's a compliment) were returning back to their Mayfair Hotel in the early hours after another Girls Aloud performance at the O2.

Wow his mouth is so white it doesn’t look human, he looks so silly. It would have been much less embarrassing to just use a specialist sonicare tooth brush and some decent mouthwash.
