From the Heart: Celeb Moms Write Open Letters to Their Kids on Mother's Day

Continuing a Mother's Day tradition, TIME.com asked the mother lode of celebrity moms to write open letters to their children in celebration of Mother's Day. "Letters from Mom" will bring a smile to the face of any mom. No matter how famous, these ladies are mothers are heart, and their lovely letters prove it.

Tina Knowles Lawson to Beyoncé, Solange, Kelly, and Angie: "Every day, I wake up thinking about how much I love, admire and cherish each of you. I gave birth to two of you, but I have four incredible daughters. Writing this brought to mind all the ways you guys have been such a blessing to me. ... Beyoncé, I wish people could see how you are when you're not in front of the camera or on the stage. How compassionate and kind you are to people, how you look them right in the eye when you speak to them. ... Solange, I knew when you were born three days late that you would walk to the beat of your own drum. You were always my rebel warrior! Always defending the underdog and fighting for what you believe in … Kelly, I know without a doubt that you were a true gift from God. You came to live with us when you were only 11 years old. You were the sweetest, most kind person I had ever met and you still are. You are also a true survivor … Angie, you are my niece, but we have always been more like mother and daughter! You were always so mature, always challenging me and questioning why…I'm often asked, what was my most proud moment? I would have to say it was at my recent wedding, when all four of you said in your own words that I taught by example and that I helped to make you the women you are today!!!! That was truly my proudest moment!"

Victoria Beckham to Brooklyn, Cruz, Harper and Romeo: "Being in a position where they live such a privileged life, it is important that our children understand humility, that they appreciate how their parents have worked very hard to create this life for the family and that they, too, have a responsibility to work hard, be respectful and never, ever take anything for granted … Like so many working mothers all over the world, I feel the constant struggle to be the best mother I can, whilst setting a good example to my children to work hard. I travel for work when it's necessary, and I miss them all the time when I am away. But they hide notes in my suitcase, which I love to find when unpacking … I love to hear their voices on the phone and seeing their faces—thank goodness for FaceTime. That sense of feeling connected makes being apart that little bit easier."

Kaitlin Olson to her children Axel and Leo: "A couple of things I hope you always remember: I'm on your side, no matter what. Even when you've done something ridiculously stupid, which you will. You can always come to me and I will help you fix it. (But you will be the one to fix it.) Be the hero! There are going to be some real turds on the playground. I want to know that you are the kids who will speak up. Focus on seeking out the good stuff instead of railing against the bad stuff. What an exhausting waste of time. You can do hard things. Take a deep breath and try again. When all else fails, ask your dad for advice. He's filled with great ideas. If you turn out half as awesome as him, we're in business. I love you. I'm so grateful that I get to be yours."

Sharon Osbourne to her children Aimee, Jack, and Kelly: "I never thought I would become a mom. None of my friends had children … Jack and Kelly, you have overcome drugs and drinking, and Aimee, you're pursuing your dreams. I'm so proud that you've all become such good, levelheaded people who care what goes on in the world. Success doesn't mean shit to me. This entertainment industry doesn't mean anything to me. If you do well and you're strong—that's what makes me feel happy, that's what makes me feel great."
