Alexandra Burke 'Found Her New Fame Mental'

Alexandra Burke has revealed how much her life had changed shortly after winning the X Factor last year.

After finding fame on the ITV1 contest, Burke flew out to the U.S. to record her debut album 'Overcome' (which topped the album charts last month).

"After I won 'The X Factor', I went on holiday. Then, when I came back, we went to New York." Recalls Alex. "I was on the phone to my management because I didn't even know how to act. What do I say when I meet the producers? Do I say, 'Hello sir?'

"And then I started in Jay-Z's studio. Jay-Z is sitting in the corner, chillin', having a conversation with me." Burke told Wonderland. "I went to the toilet and Timbaland is sitting outside. I'm singing some ad-libs and Beyonce Knowles walks in."

"That's in the first ten days of making the album. It was mental." Contact Music quotes the 'Bad Boys' singer as saying. "Mixing with people I'd dreamt of mixing with. It doesn't fit with me, with my normal life."

"I had lived on Caledonian Road in London all my life, and then I'm going for a wee and Timbaland is having a sit down. It's weird."

Alexandra has also denied she is a diva, and worries that her new found fame won't last.
