Felicity Huffman was so Desperate to be close to her idol Madonna that she once tried on her unwashed knickers!

The Desperate Housewives actress admitted she couldn't resist trying on the pop queen's undercrackers when she found them in her dressing room after replacing the singer in 1988 Broadway play, Speed-the-Plow.

Felicity - who plays Lynette Scavo in the hit Channel 4 show - told America's More magazine: "I was like, 'This is Madonna's underwear!' So I tried it on - of course, it didn't fit me."

Madonna had better lock up her wardrobe ...
