On August 4, 1961, a great man was born. He happens to be the 44th president of the United States of America. But no one was more excited to tell him happy birthday than his wife, national treasure Michelle Obama.

“55 years young and that smile still gets me every single day. Happy birthday, Barack. I love you. -mo” Also, that signature? Too cute.

This is our last time being able to say this while he’s in office. Happy birthday, Barack!

Happy 55th birthday, President Obama!
