Mel B unleashes `Scary Spice` on X Factor contestants

The talent show is still at the audition stage and the 35-year-old former Spice Girl said that she is enjoying weeding out the good from the bad.

Writing on her website, she said, 'What can I say, it's been an interesting two days. Long days, may I say? We have definitely captured some amazing talent in Brisbane. And also some very strange, funny and quirky talent- if you can call it that!

'Who'd a thought telling people they were terrible could be so much fun?!? Can't wait for you guys to see what fun and chaos we created at the X Factor auditions.

'It sucks cuz you have to see it to believe it! But one thing I can say is you will NOT be disappointed.

'Scary Spice came out in full effect! Brisbane Entertainment Centre was packed full of people booing, cheering and singing along.

'It's amazing how long you can hold your pee, as a pregnant woman, when you got work to do. Haha.'
