Michelle Obama had the sweetest message for her mom, Marian Robinson, on her 80th birthday.

On Sunday, the former first lady took to Instagram to celebrate her beloved mother with a sweet throwback photo. "Happy Birthday Mom! Your unconditional love has made me who I am today. You are my rock. My ❤. I'll always be your Miche. I love you," Obama captioned the adorable close-up snap of herself as a toddler in her mother's arms.

The former FLOTUS has never been shy about her admiration for her mother, and openly credited her for the woman she is today.

"She completely underestimates her role in who I am. She always says, 'You came here that way, I just stayed out of your way.' That's not how I saw it. My mom is an incredibly intelligent and insightful person about life in general," Obama told Essence in 2009. "From the time we could talk, she talked to us endlessly about any and everything with a level of openness and fearlessness that made us believe that we were bright enough to engage with an adult, that we were worthy enough to ask questions and to get really serious answers—and she did it with a level of humor."

Happy birthday, Marian!
