One thing is for sure – a smile is actor Rakul Preet Singh’s stress buster.

On Sunday, Rakul took to Instagram and shared one of her adorable pictures from her vacation in the Maldives. In the image, the ‘De De Pyaar De’ star can be seen flashing her million-dollar smile.

Alongside the image, she urged her followers to smile more often in life as it’s free therapy.

“Smile away !! It’s free therapy#islandlife,” she captioned the post.
