We can now confirm that Madonna is in fact planning to open this year's Grammy Awards show with, as CBS puts it, "a show-stopping number you just Can't miss."

They will begin airing today a promo spot with Madonna, looking as incredible as ever, admitting wryly, "I promised CBS that I would behave myself when I perform at the Grammys"...Yeah, right. That's our girl!

Madonna is also nominated in four categories:
Record of the Year, Best Female Pop Vocal Performance, Best Pop Vocal Album and Best Recording Package.

The 43rd Annual Grammy Awards are set to telecast live from the Staples Center in Los Angeles on February 21st. Check out Grammy.com for further details.
