Madonna is nervous about performing the halftime show at Sunday's Super Bowl XLVI, and she's not hiding it!

At an NFL press conference Thursday, the 53-year-old performer admitted to the crowd:

    "In the over 25 years of performing that I've done, I've never worked so hard or been so scrupulous or freaked out as I have been maintaining my sanity and making the most amazing show for the Super Bowl."

If you're hoping Madonna's will have a "Janet Jackson" halftime moment, don't hold your breath. Madge adds:

    "Great attention to detail has been paid to my wardrobe. There will be no wardrobe malfunctions. Promise."

The pop icon says she's been working on overcoming a recent hamstring injury with a "lot of warmups, taping and ultrasound."

Madonna revealed that she's dedicating her performance to her father.
