Today marks Michelle Obama's birthday, and to celebrate, our first black POTUS honored his favorite lady with a very heartwarming birthday wish on Instagram:

"You're not only my wife and the mother of my children, you're my best friend. I love your strength, your grace, and your determination. And I love you more each day. Happy Birthday, @MichelleObama," wrote the former president. 

Swooning! Excuse us while we grab some tissues …

Back in October, we celebrated the Obamas' 25th anniversary and highlighted some of our favorite moments of theirs. Let's go ahead and add this one to the list!  

Wishing you a happy birthday, Michelle Obama!
