Anushka Sharma looks beautiful in the Channa Mereya song in Ae Dil Hai Mushkil but she didn't feel it herself.
The actress was wearing a heavy gown and jewellery -- weighing almost 20 kilos -- and it took its toll on her.
She explains her state on mind in the video here.
The way Anushka performs in the song, of course, one would never guess it!
Ae Dil Hai Mushkil, also stars Aishwarya Rai Bachchan, Ranbir Kapoor and Fawad Khan, and will release on October 28.
