Tameka Foster Ushers Out Fiance's Mother?

Tameka Foster is taking over.

First, of course, the stylist is forcing Usher to take her hand in marriage... despite the fact that she's pregnant with another man's baby! The nerve.

Now, reports are surfacing that Foster is forcing her man to fire the woman that's been his manager from the beginning: Jonetta Patton, aka his very own mother.

"They definitely don't get along," says one source of Mama Usher and Foster, who is ten years older than the R&B superstar and who left her husband for him.

But who would replace Patton as Usher's manager? Tameka, of course. No wonder execs at Jive Records are concerned. Foster knows as much about music as Keira Knightley knows about eating.

For now, this is just making the celebrity gossip rounds. The story may not be true. But if it is, we know one thing for sure:

Other fiances, such as François-Henri Pinault - and Ryan Piers Williams once he actually commits - would never act like this.
