In what seems like an open challenge at the throne of the two hottest Bollywood item queens, Sherawat danced to an item song at Yashraj Studios, whose words blatantly mocked Katrina Kaif and Malaika Arora Khan.

Mallika sang, "Munni bhi maani aur Sheila bhi maani, Shalu ke thumke ki duniya deewani" (Munni and Sheila both agree the world is crazy about Shalu's moves).

Apparently Farah Khan, the choreographer of the songs Munni and Sheila, was approached to do Sherawat's Shalu ke thumke. But Khan begged off, saying she only choreographs for very close family friends.

"By openly singing that she's better than ‘Munni' and ‘Sheila', Mallika is sending out a clear signal to the entertainment industry," a source said.

"Mallika wants to position herself as the No 1 item queen of Bollywood. She feels her Maiyya maiyya in Guru came long before My name is Sheila and Munni badnaam."
