Cocozza, 18, is currently competing on the UK series and has admitted he's been going out and getting drunk a lot despite a ticking off by mentor Gary Barlow.
Lloyd, also 18, isn't sure if he is taking the show, and his career, seriously.
She said to Real Radio: 'He looks like he's having a whale of a time but, at the same time, does he want a career? That's maybe why the public aren't warming to him.'
She was also asked if he tried to chat her up backstage after her performance on the show.
She said: 'Oh no, I wouldn't have that. I would have told him where to go straight away. I stayed clear of him.'
