Miranda Cosgrove performed in concert on NBC's "Today Show" on Monday. This was the "iCarly" star's live TV debut. She had a little bit of a punk vibe with a mostly black outfit, which included platform boots, a leather and sequined jacket and ruffled purple and black skirt.

Miranda's debut CD "Sparks Fly" is in stores now and features her smash hit single "Kissin U."

An all-new episode of "iCarly," "iSam's Mom," is set to premiere Saturday, Sept. 11, and features a very special guest appearance by Jane Lynch as Sam Puckett's (Jennette McCurdy) mother.
