Singer Madonna and her husband, film director Guy Ritchie, are once again the subjects of artist Peter Howson's work -- much to their dismay.

The new painting depicts an extremely muscular Madonna lying naked on a bed with Ritchie laying his hand on her thigh, also grotesquely muscled, The Sunday Times of London reported.

This is the third painting Howson has put the couple in. It was reportedly done as a provocation toward Ritchie.

Matthew Flowers, Howson's dealer, said Ritchie was unhappy about the two earlier paintings from 2002, which also showed the singer nude.

"Peter's a bit obsessed with Madonna," said Flowers. "There are strong rumors that Ritchie was very jealous of the earlier pictures and wanted to knock Peter's block off."

"It's probably a subconscious thing that I've got with Ritchie and yes, I've heard that he may not have liked my other portraits," Howson said. "I've never actually fancied her but I admit I've got a thing about her."
