She already has a reputation for being domineering and controlling, but now it seems that Tameka Foster, Usher's wife and baby mama, is mixing it up with Usher's video co-stars.

The New York Post reports that Tameka intentionally dressed Keri Hilson, a singer who plays Usher's love interest in his latest music video, "like an extra" and was "guarding like a watchdog" during the shoot. "It was ridiculous – she knows Keri and knows she's no video ho," says the source.

Usher's manager says that Keri was fine with Tameka's styling choices and that the shoot went "brilliantly."
