Beyonce has bust up with Janet
Beyonce Knowles and Janet Jackson are at war, after the Destiny's Child babe snubbed a duet with the superstar singer.
The pair were due to perform together earlier this year - but Knowles didn't want to be associated with Jackson following her controversial appearance at the Super Bowl in February, at which she accidentally exposed her bare breast.
A source says: "Beyonce pulled out of a duet with Janet after the Super Bowl nipple fiasco. Janet was very hurt by the move."
