As the superstar, 53, promotes her directorial effort W.E. at the Venice Film Festival, a French magazine claimed she took a shot at her pop heir Gaga, 25.
Madonna was quoted as allegedly sniping: "As for Lady Gaga, I have no comment to make about her obsessions having to do with me because I don't know whether her behavior is rooted in something deep and meaningful, or superficial."
The "Live to Tell" singer definitely did make a nasty comment about hydrangeas, however. Just before a W.E. press conference in Venice, Madonna received a bouquet of hydrangeas from an adoring male fan, and a video camera caught what happened next.
"I absolutely loathe hydrangeas," the superstar sniffed. "Obviously he didn't know that."
Says the rep: "The hydrangea incident is so ridiculous..It's not like she said she hated warm chocolate chip cookies and milk and little puppies!"
