From the Boston Globe:

Among Leslie's contributions so far: a bona fide hit for model-turned-singer Cassie (the pop-funk bauble "Me & U"), a near-hit for himself ("Diamond Girl," the synth-driven first single from his forthcoming solo debut, due out in late August), and production work for everyone from Britney and Beyoncé to Usher and Danity Kane. He's signed as an artist to Universal and as everything else to Sean "Diddy" Combs's Bad Boy Entertainment. Combs heard "Me & U" while partying at New York's Bungalow 8 and shortly after made Leslie an offer he couldn't refuse: a joint artist deal for Cassie and a distribution deal for Leslie's label/production/media/marketing company, NextSelection Lifestyle Group.
