'Humpty Sharma Ki Dulhania', which released this Friday, had an impressive opening at the box-office.
The proud father took to Twitter to congratulate both the actors and even posted a picture of them.
"The hit team! But beware kids.. Success is a lousy teacher. It makes even the wise believe that they can never fail," Mahesh posted.
Produced by Karan Johar and directed by Shashank Khaitan, the film is a modern take on Shah Rukh Khan-Kajol starrer hit 'Dilwale Dulhaniya Le Jayenge'.
This was Alia and Varun's second film together after their debut outing 'Student of the Year'.
