The "Haider" star also shared an image of himself pouting while sitting in a car.
"Thank you thank you all seven million of you... What a Shaandaar feeling," Shahid tweeted on Wednesday.
Shahid joined the micro-blogging site in July 2009 and stays in constant touch with his fans through it.
The actor, who grabbed headlines for his marriage with Delhi-girl Mira Rajput earlier this year, will be coming on the silver screen for the first time post his wedding with "Shaandaar", opposite Alia Bhatt.
"Shaandaar" is a romantic comedy against the backdrop of a destination wedding. Produced by Dharma Productions and Phantom Films, the film is directed by Vikas Bahl, and will release on October 22.
