Lil Mama might just have stole the show last Tuesday at the Highline Ballroom's Spankrock/Ghostface extravaganza with skills, poise and lots and lots of rhinestones. The teenage MC performed her debut single "Lip Gloss," her Jay Z remix ("Show me what you got, lil mama" - get it?), and two other verses - one from her take on Rhianna's "Umbrella" and a brand new, double-time accapella verse she said was going to be on a remix to the Avril Lavigne single. The quickie set got us hyped to hear more from her (although to be fair, we've been hyped since we had her on our East Village Radio show months ago), so it's convenient that a new joint called "On Fire" appeared on the webs, produced by Marvelous J. You're telling us homegirl can sing, too?!
