Ayushmann Khurrana seems to be hooked to the Baby Doll song from 'Ragini MMS 2'. Now that's one song he is found humming all day, these days.

While shooting a courtroom scene recently for his film' Dum Laga Ke Haisha', Ayushmann sang Baby Doll to the tune of his own tabla on the court-room table.

Now wonder what the judge had to say about this impromptu jam session.
