"Being a mom is one of the biggest joys of my life. I have learned so much from my three kids… patience, kindness, humility, creativity and of course, how to tell a great knock-knock joke!," she wrote.

"To my wonderful kids, I love you more than you will ever know (you will figure that out as soon as you have your own kids.)," she continued. "Always know how grateful I am every day I get to be your mom!!"

Meanwhile, Dancing With the Stars' Peta Murgatroyd celebrated her first Mother's Day with baby Shai in a sweet pic shared by her fiancée, Maksim Chmerkovskiy, who captioned the pic: "Happy first official Mother's Day my love."

Tom Brady pulled double duty on Instagram, wishing a happy holiday to the moms in his life -- his own, as well as wife Gisele Bundchen.

"Happy Mother's Day Love of my life!" the NFL quarterback captioned a pic of Bundchen on a horse with the couple's 4-year-old daughter, Vivian. "We couldn't have wished for a mother to love us the way you do! We love you so much! Jack Benny Vivi and Papai (and Lua Scooby and Fluffy too ?)."

And for his mom, Brady posted a sweet family photo, writing, "Happy Mother's Day Mom. Looking at this photo makes us all so proud. Without you none of this is possible. You are the kindest, gentlest, most loving mother a son could ever ask for. You have taught us what strength really means. Family is everything. We all love you so much."
