The show's runner up overheard nasty comments

Rebecca Ferguson didn't let the nastiness get her down

Even X Factor sweetheart Rebecca Ferguson couldn't escape the bitching in the contestants' house.

Rebecca, 24, was on the receiving end of a bit of jealous moaning from a member of Belle Amie.

'Rebecca had come back from rehearsals and heard whispering from the lounge next door,' an X Factorinsider tells Now.

'One of Belle Amie started saying stuff about Rebecca...that rehearsals took ages and Rebecca was always given a lot of time.

'It was quite mouthy and they weren't talking in a nice way.'

Gentle mum-of-two Rebecca - who finished runner-up to Matt Cardle - decided not to confront the grumbling girlband member.

'Rebecca was very dignified and just said she was going to use the bitching to spur her on,' says our source.

'She's a lovely lovely girl.'
