She wore a black pleated silk skirt with lime colored sleeveless top.
Katrina, 26, was a bonus attendee at the event; as per the announcement, only the male cast - Hrithik Roshan, Farhan Akhtar and Abhay Deol - should have been there, along with writer director Zoya Akhtar.
It sure seemed like a last minute decision on Katrina's part, going by her dress at the time of her arrival: black tights, red tunic top and a striped sports jacket, as if she was on her way to the gym when something made her change her mind!
After arriving at the venue, she quickly changed into a new set of clothes, a casual flirty outfit: loose tank top, voluminous silhouette A-line short skirt and black ankle strap thong flats. She glammed it up with black hoop earrings.
Her hair, styled straight with a side parting, draped her shoulders. Plum lipstick and lash extensions rounded her alluring looks.
She posed for photogs with Hrithik Roshan; the two are paired in the film.
Hrithik was dressed to beat the heat in blue crew neck tee, faded blue jeans and white tennis shoes, sans laces!
Abhay Deol sported a beard, a less dense version of what cousin Sunny Deol is going around with these days.
Abhay's facial foliage likely comes from his look in his under production film Shanghai, a political thriller directed by Dibakar Banerjee.
Farhan, who is also the producer of the film, and sister Zoya looked chilled hosting the event.
