Lil' Kim said she was "disappointed" when she was convicted of perjury last week for lying to a grand jury about a 2001 shoot-out involving her manager and another friend. She's got to be frontin'. The risqué rapper, whose star has tarnished a bit in recent years, is facing the ultimate show-biz pick-me-up: jail time. What's more, it's for protecting her crew with a completely hopeless lie. She said she didn't see the men at the scene of the crime, even though a security camera had footage of one of them holding an elevator door for her. Did someone say "street cred"?
