After Welcome, Billu Kalpana Patowary sings for Akshay Kumar & Katrina Kaif's - De Dana Dan.
Kalpana is reportedly set to testify in court as part of a legal battle with a Delhi based music company and a singer who alleges that Hat Ja Tau Pacche Ne,a super hit Haryanvi song is his song as their own. They have filed a lawsuit at Kalpana over claims of their copyrited song. They insist that the tune may be in English but are suspiciously similar to that hit Haryanvi song. Lawyers for the trio,asked to throw out the case but Delhi court has now given the go ahead for the copyright case. Kalpana is expected to take the stand, because her legal team claims she has no idea about the track. Says Kalpana ….well the north Indians are going to love this song , and Pritam has deviously picked this immensely popular Haryanavi song Hat Ja Tau Pacche Ne for creating the funny song Hotty Naughty. De Dana Dan is the return of the hit film Hera Pheri with the hit pair AKSHAY KUMAR & KATRINA KAIF with music by Pritam. So is it will be another hit song after billu bhayankar (BILLU BARBER) & ek uncha lamba kad (WELCOME) from a hit singer.
