Talk about cheek! Robbie Williams has stripped nude for his fans on his wife Ayda Field's Instagram account.
The star strutted into view, as naked as the day he was born, with only a cake covering his crown jewels.
Robbie had been joking earlier about whether it would be better to have the power of invisibility, or the power to eat sweets with no consequences. The singer chose the latter.
Then he appeared nude, joking: 'Look, floating cake! I'm invisible!' before his wife reminded him that being invisible wasn't his choice.
