Today is a special day for a very special former First Lady of the United States. January 17th marks Michelle Obama's 54th birthday and her husband, Barack Obama, started her day off with a bouquet of flowers and a card sitting on her office desk this morning. 

Michelle posted a photo to Instagram thanking Barack as well as the many fans who have also sent her letters for her birthday. "You’re my best friend, biggest fan, and getting notes and flowers from you will never get old," she says of Barack. "And to the many people from around the country who sent cards and posted on social media, you have no idea how much we love hearing from you." Check out the full post below.

Just three months ago was Michelle and Barack's 25th anniversary. The former president surprised his with a video of him stating how much love he still has for her during her speech at the Pennsylvania Conference for Women.

"Listen, I know you are with all these important Pennsylvania women and you're sharing the stage with our buddy Shonda Rhimes, but I had to crash this party because today we have been married for 25 years," he said in the video. "Now, the idea that you would put up with me for a quarter of a century is a remarkable testament to what a saintly, wonderful, patient person you are."
