Speaking to the Daily Mail newspaper, the star explained that his problems with the Spice Girl began when she turned up to work as a judge on Popstars: The Rivals and sat her dog on her lap, despite there being a rule against animals on the show:

"When she came in and put the dog on her lap, I thought 'What am I actually doing here?' In our contract with ITV there were all these rules about what you could and couldn't do on screen."

"One of them, I always thought, was that no animals were allowed. So all the TV executives were freaking out about there being a dog in the studio."

Although Waterman explains there is no bad blood between the pair, he thinks she was massively affected by her career as a member of one of the modern world's most famous girl groups and expects that it caused her to be somewhat disillusioned:

"I didn't have a problem with her as a person. She was just a little bit wild. Well, maybe wild isn't the right word, she's just been in the Spice Girls, which must have been a surreal experience. You think, 'Hang on, this girl's not in the real world'. She's lost all touch with reality."

"She's got a completely different view of the world than anyone I know. That's what happens to pop stars sometimes."
