Gushing over his `extraordinary smart` wife Katherine Schwarzenegger, who turned 32 on Monday, actor Chris Pratt penned a heartfelt note on his social media account. Taking to his Instagram handle, Chris shared a series of pictures of his `beautiful` wife and wrote, "Happy Birthday Honey! You are such a wonderful wife, mother, step-mother, and life partner. I simply can`t imagine how lost I`d be without you." 

He continued, "You`re beautiful, tough as nails, reasonable, deeply thoughtful, extraordinarily smart, you`re a complete boss, eternally driven and you communicate like no other. Thank you for everything. Thank you for being so instrumental in my growth over the past few years. We fit so perfectly into each other`s lives that our Union is a daily reminder that God is looking out for us."
