Alexandra Burke's celebrity friends

Alexandra Burke emails Beyonce Knowles all the time.

The 'Bad Boys' hitmaker has struck up a close friendship with the US singer and though they struggle to find the time to see one another, remain in constant contact.

Alexandra said: "We talk through email. She's a lovely woman, the most whole woman I've ever met and with her success you wouldn't expect her to be, but she is. She's the ultimate diva.

"We just talk about how everything is going. She asks me what I am up to, and how my career's going. It's just normal, weirdly normal."

Beyonce isn't Alexandra's only famous friend.

The singer has remained so close to Cheryl Cole - who was her mentor when she won UK TV talent show 'The X Factor' in 2008 - that she was even invited to spend Christmas with the Girls Aloud star and her husband, soccer star Ashley Cole.

She told more! magazine: "We're on the phone all the time - it's ridiculous. She even asked me to come round on Christmas Day but I said I was spending it with my family.

"It's just like she's my second family, me and her always eat spaghetti together. She's such a lovely woman but my God she's feisty."
