One lucky fan will have an opportunity to take the stage with Katy Perry on music’s biggest night.

Between today and February 6, fans may upload video footage of themselves singing a portion of Katy’s Summer smash “I Kissed a Girl” to www.cbs.com/grammys for the chance to sing with her at the 2009 Grammy Awards next month.

“We are very excited that this year’s installment of My Grammy Moment allows numerous online fans to be an integral part of a performance,” Recording Academy President/CEO Neil Portnow explains.

The 51st Annual Grammys will broadcast live from the Staples Center in Los Angeles February 8 at 8 p.m. on CBS.
