'Happy Bday Kimi.
In a sea of botox-you are my real.
In a spectrum of toxic- you are my happy pill.
In the world of spineless you are my titanium.
In a cluster of uncertainity you are my constant.
In a world of ifs, buts, more butts, entitlement and hustle - you are my FOREVER!
Thank you girl for being the vitamin K in my life. Without you...my smile would not beam as much!
Love you to the moon and back... Stay mad...keep whispering aloud in wild abandon....keeping caring while you munch on your Vegan delights...keep dancing on bar stools like no one is watching...keep driving me crazy... driving me up the wall!
Because woh toh aap ka haq hain.
Thank you for everything.
This world is a better place because of your happyness and how you make bikinis looks better. Big thank you meri jaan!! Tu nahin 'hottie' toh mazaa nahin hota.
Happy bday once again.'
