Mrunal Thakur rejected Aamir Khan's Thugs of Hindostan because of this

She started her career with the hit
television show Kumkum Bhagya and later
appeared on a dance reality show with ex
Sharad Tripathi. She's currently waiting for
the release of her Hollywood debut, Love
Soniya.
Apparently, Aamir saw rushes of her show
and movie and sent her a message and
suggested she comes on board for Thugs
of Hindostan. But she turned it down. Wait,
WHAT!
Now as we all know, whichever newcomer
signs up with Aditya Chopra's Yash Raj Films
has to sign a three-film contract with the
production house. And everyone from
Ranveer Singh, Anushka Sharma,
Ayushmann Khurrana have done it.
Mrunal felt signing a three-film deal would
affect her international career hence she
turned it down. What's more Mrunal had
even auditioned for Sultan opposite Salman
Khan but tht didn't pan out well.
