London, October 5 : Madonna and Lady Gaga drew gasps from the audience as they fought on live TV.

But it turned out to be a sketch for US hit show Saturday Night Live.

The singers were performing on made up show `Deep Dish' when they broke into a fierce brawl that involved hair pulling, wrestling, and put-downs.

Host Kenan Thompson tried to separate the warring pop stars on the couch, but in vain as they continued to exchange insults.

"Guess what, Madonna? I''m totally hotter than you," the Sun quoted Lady Gaga as saying.

Madonna got back, saying: "I''m totally taller than you."

The Queen of Pop added: "What kind of name is Gaga? Sounds like baby food!"

The `Poker Face' hitmaker replied: "The kind of name that is number one on the Billboard chart." (ANI)
