The 26-year-old actress will take on a glamorous look in the scenes, which she shot in Bangkok over three days.
Khan told The Times of India: "It's a cameo with a club song. Salman offered me to do this and I would never say no to Salman.
"I also found it quite exciting, especially after Veer because there I had a totally Indianised look, totally covered and after that it is like total 360 degree makeover.
