The star, 56, surprised onlookers and made headlines around the world 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 on Saturday — that her daughter Lourdes was mortified.
“I couldn’t help myself. One is allowed one cheeky moment per awards show,” she said. “If Lola [Lourdes] is around, she will definitely give me the once over and say: ‘Oh mum, no, you are not leaving the house like that.’ She did take a picture of my butt sticking out and sent it back to me saying ‘mum, really?!’ and I said it was a wardrobe malfunction.”
Madonna, who caused a sensation when she fell during her Brits performance last month, said a voice in her head told her to flash at the Grammys.
“I swear to God, it was after I left the big pen you have to stand in where all the paparazzi are standing and I turned around and that naughty devilish voice in my head — sometimes I tune into it and sometimes I shut it off completely— said ‘lift up your skirt’ and I did.”
The mother of four said that, despite her fame, her children are not aware of her early hits such as ‘Holiday’.
“They don’t even know [what] that is... Honestly they don’t go past ‘Vogue’... I mean it’s just, it’s another century isn’t it? It’ll happen. They’re in the ’90s [songs] right now, I can’t ask them to go back another decade.”
The star said it felt as if she was somewhere “exotic” when she lived in England with then husband, film director Guy Ritchie.
“I’d never been horseback riding before, I didn’t know about fly fishing, I never drank ale,” she said. “I really enjoyed living here and I love adapting to new environments and I did enjoy myself. I learned a lot.”
And she said of her tough image: “People think that I am an armadillo and they can say what they want and nothing is going to bother me and that’s simply not true.”
