The official reason given was that Mika Singh already had a solo item song in the film and dancing with Rakhi would only take away the credit for that song.
Getting sarcastic, Mika Singh said, “Main Rakhi ke saath perform karu, aisi uski kismat kahan (she is not so fortunate that I will dance with her)".
Rakhi reacted and said, “I just got to know that my enemy is not doing the item song with me. It"s totally his loss. I guess, he is just too old to perform on an item number with me."
