Here's how Fawad and Alia celebrated Sidharth's birthday

There was no cake or birthday bumps when Sidharth Malhotra rung in his 31st birthday yesterday with his Kapoor and Sons co-stars. Instead, the Bollywood actor was in for a special surprise!

Pakistani heartthrob Fawad Khan and Bollywood star Alia Bhatt made sure they celebrate their friend's special day in a unique way -- by cutting a watermelon instead of a cake!

Alia took to Twitter to share how "cool" the trio is:

She also sent a special wish to her rumoured boyfriend:

Following suit, Kapoor and Sons director Karan Johar and Fawad also wished the Ek Villain actor:

But that's not it! The day ended with another bang as Fawad made his Dubsmash debut alongside Alia and the birthday boy himself.

The trio lip-synced Bollywood's iconic birthday song Baar Baar Din Yeh Aye showing that there is no stopping the actors from having some fun time even while they are on the sets of their upcoming film.


Fawad -- who just made his Instagram debut as well -- shared the video that we can't get enough of:
