In September 2002, Toni Braxton sent an advance copy of "Me and My Boyfriend" to Def Jam president Kevin Lilles. Shortly thereafter, according to Braxton, Jay-Z and Beyonce released a new single whose tune was almost identical to hers. Their song's title? "Bonnie & Clyde"!
[Bonnie & Clyde, of course, were notorious robbers. "I'm not hating on Beyonce or anything," Braxton remarked, "but (they) are messing with my money. They're trying to steal my mojo!"]
