Emraan Hashmi, the suave conman from Raja Natwarlal, danced with his alluring co-star Humaima Malick in the upcoming song Flip Your Collar, which was shot at a mall in Mumbai recently. Humaima, a top Pakistani actress, oozed oomph as she followed instructions from Remo D'Souza, the song's choreographer. Emraan being the professional that he is, underwent a minor medical procedure in the morning, where he got a protrusion removed from his nose, and came straight from there to shoot this song.
