A highly placed source in Kelly Rowland’s camp exclusively tells us she fired manager Mathew Knowles yesterday. The source tells us a big argument went down and at the end, Kelly kicked her “Dad” to the curb. The source goes on to say this is sure to put a strain on Kelly and Beyonce’s relationship.

We are pretty sure this has something to do with the Knowles clan trying to sabotage Kelly’s career for years. Beyonce is almost the only one left from Destiny’s Child, imagine that.

We can tell you that we spoke with a Knowles insider last week who told us that if Kelly were to leave Mathew, she’d have to pay “a pretty penny.”

Why, you ask? Mathew has an airtight contract with Kelly. Explains the insider, “He’s contracted to get his management fee from Kelly whether he manages her on NOT.”
