Chris Evert penned a similarly touching message for her "amazing" son Alexander Mill when he turned 33 in October.

"Happy 33rd Birthday to my amazing son Alex ❤️. Thank you for being my rock the last few years when I've needed you. Watching you grow into the kind and caring person you are today fills me with pride. Here's to many more years of love, happiness, and adventure! ❤️ Mom," Evert captioned her Instagram post.
