NEW SONG FROM CASSIE CALLED "WHAT SHE DONT KNOW" & IT'S THE NEW JUMPOFF ANTHEM! I BET ALL THE TIGER CHICKS OUT THERE GOT THIS ON THEIR IPOD!

R&B singer Cassie’s new song and all we can say is . . . WOW!!! In her new song, entitled What She Don’t Know, the girl is taking some OBVIOUS shots and Diddy’s OTHER CHICK, his baby’s moms Kim Porter. This may be the most BRAZEN jumpoff pride anthem that we’ve ever heard.
