Misha B would have a “heart attack” if Beyoncé Knowles made an appearance on ‘The X Factor’. 

The 19-year-old singer admitted if the ‘All The Single Ladies’ hitmaker - who is the former Destiny’s Child bandmate of Misha’s mentor Kelly Rowland - came to see the ITV1 show, she wouldn’t be able to cope with being face-to-face with her idol. 

Asked whether Beyoncé will be making an appearance in any of the live shows, Misha told BANG Showbiz: “Kelly won’t tell us. I don’t think she wants to give me a heart attack just yet. I don’t know how I’d cope if I met her. 

“Beyoncé and Adele are the people I’d most like to perform alongside.”
