Madhuri Dixit and Co from the new dance-based reality show, So You Think You Can Dance, were greeted by a surprise visitor on Thursday as they shot in Goregaon's Filmistaan studio. Turns out, one of the guys from the show's production team had to bring his pet dog to work as there was no one home to look after it. The considerate master locked his pet in a room in the studio so he wouldn't get in anybody's way. At a later point during the day, the dog somehow managed to escape the room and strayed on to the sets, catching everyone, including Madhuri who was particularly jumpy at the sight of the uninvited guest, off guard. Now we know what truly makes this screen diva's heart go 'dhak dhak'.
