Louis Walsh gets a drenching from a young hopeful in tonight's episode of The X Factor.

18-year-old Debbie expects to make a huge impression on the three judges, admitting that she dreams of performing on-stage "with millions and millions of people screaming".

"I've got The X Factor," she explains confidently. "I know I can win, I've just got it basically. I'm amazing, I'm pretty damn good. Nobody comes anywhere near close to me."

However Debbie's performance of If You Believe by Whitney Houston and Mariah Carey fails to impress the three judges, with Louis encouraging her to accept that she is "not very good".

"You are the one person I didn't want to see today because I really want to slap you now," Debbie replies angrily. "I'm not a good singer? That is why I have been a singer since I was 6 years old and everyone I've ever met, even people who don't like me have come up to me and told me I've got an amazing voice."

After the judges comment on the teenager's "bad attitude", Sharon Osbourne decides to escort her out of the room, but Debbie returns moments later and attempts to throw Simon's glass of water over Louis. Spotting what she plans to do just in time, Louis throws his own water and both end up soaked.

"You threw water over a contestant, Louis!" Simon exclaims. "You're not supposed to do that. You can't throw water over the singers, Louis!" But Louis refuses to apologise, protesting: "She was doing it to me."

The X Factor airs at 7.20pm tonight on ITV1.
