Kate Hudson Shares a Heartfelt Message For Son Ryder on His Birthday: "I Will Always Be There"

Kate Hudson's firstborn, Ryder Robinson, turned 13 years old on Saturday (yes, he shares a birthday with Blue Ivy Carter), and to mark the special occasion, the actress took a walk down memory lane on Instagram. Along with an adorable throwback photo of Kate and Ryder at the beach, the proud mom reflected on the joy of motherhood. Her message reads as follows:

"Thirteen years... Today I reflect on how lucky I am to have spent my entire adult years being Ryder's mother ❤️ My dear Ryd man! Today you are 13! Hard to believe but I'm staring right at you and my goodness yes you are a teenager! I couldn't be more in love with who you are as a person and who you are growing into as a young man. Smart, funny, joyful, tolerant, perceptive, empathetic, loving, you continue to maintain the beautiful attributes of your true nature and I will always be there as your touchstone to help nurture them or rediscover them if they ever get cloudy. But watching you independently keep these characteristics close and alive has been a wondrous journey in which I look forward to witnessing every waking hour. Happy Birthday baby!!! 🎂 13 is looking pretty awesome so far!!! I love you ❤️ #RyderIsThirteen #HappyBirthday #ProudMama"

Kate and ex-husband Chris Robinson are both parents to Ryder, while Kate shares 5-year-old son Bingham Bellamy with ex-fiancé Matthew Bellamy.
