At the recent London X Factor auditions Simon was whipping the audience up into a frenzy and then said, "Now who would like to hear from Cheryl.... Tweedy?" he then looked down at her and said, "It is now isn't it?"

Apparently the crowd went wild and Cheryl was beaming at the level of support.

Meanwhile she's not long returned from her holiday in the safari with dancer Derek Hough.

Neither of them are making any comments on the nature of their relationship but lots of 'sources' including Derek's dad, are claiming that the pair are in love.

What do you think? Do you buy it?
