Three things I don't understand
First, was Stacey always like this? If no, why did she start?
Second, what on earth is Tony talking about when he accused Nessa of blabbing about what they talked about? As far as I can see, all they talked about was how he went to see "Bend It Like Beckman" a bunch of times. They didn't even date, at least not in the movie. Vanessa didn't tell Stacey about her conversation with Tony - instead, she was talking about some other guy and Nikki and Stacey had no clue of what Tony and Vanessa had spoken about. SO what could Nikki have said to Tony to make him so mad at Nessa.
Third, Stacy's mom tells Vanessa's mom that Vanessa stole Stacey's bf. Now, STacey's mom HAD to know that wasn't true; she'd never even MET or heard of this boyfriend. Vanessa and her mom seemed close enough that Nessa might have least mentoned a relationship with Tony. And Stacey's mother HAD to know Stacey never even HAD Tony as a bf.
