Dannii Minogue reckons Robbie Williams should hit the gym before he appears on The X Factor.
The Angels star, 35, has been confirmed to perform on one of the live shows.
‘Robbie will be great - if he gets himself in shape first!’ says Dannii, 37.
‘He is such a showman, he never fails to deliver. I think he'll come right out to the audience and the judges like Beyonce Knowles did last year, and put on a really great performance.’
Madonna and Whitney Houston are also rumoured to be appearing on the ITV programme.
‘All of my gay friends are begging me for tickets to the Madonna night!’ Dannii tells The Sun. ‘It would be amazing to have her on.
‘I'm looking forward to Whitney, too. There was pressure on us after Britain's Got Talent to be as big and as good, and I think we will be.’
