Jazz singer Amy Winehouse is unhappy with Natasha Bedingfield.

Amy has decided that she "doesn't like" Natasha, who apparently has her sights set on Winehouse's boyfriend, Tyler James.

"Natasha Bedingfield fancies my man, Tyler," Amy told the Sunday Mirror. "I don't like her."

However, Winehouse has another boyfriend to worry about - she has admitted that she is dating a second man, George.

"Tyler knows all about it," she added. "He's cool with it. George is so cool. But Tyler is my baby."
