"We are really, really excited and we can't believe that it's been four years and all we want to say is, 'Thank you, Thank you so much'," said Alia. "There's one man we want to thank - Karan Johar. Me, Sid and Alia, thank you from the bottom of our hearts. We are, who we are, because of you," added Varun.
Alia and Varun made the video while they were in Singapore shooting for their upcoming film Badrinath Ki Dulhania, which is again produced by Karan's Dharma Productions. Here's what they've said:
Sidharth, who busy with his own projects, shared his own video:
Meanwhile, Karan Johar tweeted the film's poster with a sweet message:
After starring in the 2012 film, Alia Bhatt, 23, went on to do critically acclaimed films like Highway and Udta Punjab. She also featured in typical masala films like 2 States, Humpty Sharma Ki Dulhania and Kapoor And Sons. Barring Shaandaar, Alia has only struck gold at the box office. She'll be next seen in Gauri Shinde's Dear Zindagi co-starring Shah Rukh Khan.
Varun Dhawan, 29, too had a blockbuster journey in Bollywood for four years. Films like Main Tera Hero, Humpty Sharma Ki Dulhania and ABCD 2 made good bucks at the box office while with Badlapur he earned critical acclaim.
For Sidharth Malhotra, 31, things have not been so smooth. Hasee Toh Phasee, Brothers and Baar Baar Dekho did not fetch much. Though Ek Villain and Kapoor And Sons have been his saving grace.
Karan Johar is gearing up for the release of Ae Dil Hai Mushkil in which he's directed Ranbir Kapoor, Anushka Sharma, Aishwarya Rai Bachchan and Fawad Khan. Alia, Shah Rukh and Lisa Haydon have cameos. The film releases on October 28 along with Ajay Devgn's Shivaay.
Meanwhile, a sequel to Student Of The Year, with Tiger Shroff in lead role was announced recently.
