Alexandra Burke has warned Joe McElderry to expect his life to radically change after winning The X Factor. The ‘Bad Boys’ singer, who won the ITV1 show last year, told McElderry to “ignore” people who claim to be close to him in the wake of his success. “You get family members you’ve never heard of and people who bullied you at school wanting to be your friend. Ignore it,” she told The Sun.
