I couldn't help flashing bum - Madonna
Madonna has said she "couldn't help myself" when she flashed her bottom at the Grammys.
The star (56) surprised onlookers and made headlines when she showed off her posterior, in fishnet tights and a black thong, on the red carpet.
She told The Jonathan Ross Show, to be broadcast on ITV this Saturday, that her daughter Lourdes was mortified.
"One is allowed one cheeky moment per awards show," she said. "If Lourdes is around she will say, 'Mum, no, you are not leaving the house like that!'
"She did take a picture of my butt sticking out at the Grammys and sent it back to me saying, 'Mum, really?!' I said it was a wardrobe malfunction."
Madonna (inset) said a voice in her head told her to flash at the Grammys.
"It was after I left the pen you have to stand in where all the paparazzi are and I turned around and that naughty devilish voice in my head said, 'Lift up your skirt'. So I did."
She said of her tough image: "People think I am an armadillo and they can say whatever they want and nothing is going to bother me, but that's simply not true."
