Cher Lloyd linked to fellow X Factor contestant Aiden Grimshaw
The pair - who both like to pull some weird faces when they're singing - are said to have grown close during the boot camp stage of the ITV show in London.
'Cher had a crush on Aiden from the start but it took a few weeks for the feeling to become mutual,' says a source.
'They aren't being overly affectionate with each other in front of other cast and crew members, but they have been spotted on more than one occasion.
'The minute they get some free time they seek each other out.'
Cher, 17, has previously dismissed claims she's mad about fellow contestant Liam Payne, 17.
'He's good-looking but not my type,' she said. 'I only spoke to him three times [at boot camp]. I didn't fancy him. There's definitely nothing between us.'
Cher and Aiden, 18, will be seen taking part in the judges' homes section this weekend.
