Tameka Foster may very well be a nice lady at some point during the day, like right when she wakes up in the morning or before she goes to sleep. But during that in-between time? By most accounts she's pretty damn unpleasant. Take Usher's recent video shoot, for instance. Rumor has it Tameka was not happy that Usher handpicked singer Keri Hilson to be his love-interest in the video and went on a sabotage mission — styling her poorly, not letting her use her hairstylist, and banning her choreographer from the set. Benny Medina, Hilson's manager, played nice and said, "Keri could not have been happier with Tameka's choices in the styling, hair and makeup . . . [the choreographer] was flown out and arrived a day late to do Keri's choreography, and was on-set at all times. The shoot itself went brilliantly."
