Karan Johar may have just scored the ultimate offer from none other than British Pakistani singer Chahat Fateh Ali Khan, who’s ready to star in Johar’s films for ‘free of charge’ This generous proposal followed Johar’s Instagram story where he shared Khan’s cover of ‘Tauba Tauba,’ calling it a “must-watch” with a heart emoji. The original song, a viral hit by Karan Aujla, featured in Johar’s production Bad Newz starring Vicky Kaushal.
