Anushka, who is learning how to wrestle for the film, has her arm around Salman in the image that was posted on the film's official Twitter page. Both the actors are seen in blue tracksuits sitting near what seems to be like a wrestling arena.
The image was captioned: "Haryana ka Sher aur Haryana Ki Shaan ka ghana ishq hai takkar ka. This #Valentines Day, celebrate the love of equals. (Haryana's tiger and Haryana's pride in a keen tussle of love.)"
"Sultan" will bring Anushka and the superstar, who is playing the role of a wrestler in the film, on the big screen together for the first time.
The Ali Abbas Zafar directorial is being produced by Aditya Chopra under Yash Raj Films banner.
The film also features Randeep Hooda and Amit Sadh.
