She was on The X Factor in 2010 alongside One Direction and Cher Lloyd. She came seventh and was, how do we put it? a controversial contestant. She was in the bottom two four times but the judges kept her in.
Last month we wondered whether she was going to enter the 'normal' Big Brother house but now it looks like she's going into Celebrity Big Brother.
According to The Sun, while on a flight from Atlanta to London the 30-year-old was talking loudly and was overheard saying: "I shouldn't tell you this, but I'm going to be in Celebrity Big Brother."
And a source told the newspaper: "Getting Katie in the show is bound to ruffle some feathers – she might be one of the biggest egos the house has ever featured.
"It means the house has a ready-made baddie, but who knows, she might win people over."
