Happy Birthday, Milo!
For her son Milo's 10th birthday, actress Liv Tyler, 37, took to her Instagram page to share a sweet throwback snapshot of him from the day he was born in 2004.
"Milo William Langdon, Happy birthday my darling boy," the pregnant star began the message to her son, whose father is Liv's ex-husband, musician Royston Langdon.
"10 years ago you arrived, the most beautiful gift of my life, my greatest love. I am soooooo grateful to be your mommy," she wrote.
Later that day, Liv also posted a photo of Milo's birthday cake with the caption, "Cake in a box!!"
Milo is the 'That Thing You Do!' actress' only child, though she is expecting another child with her sports and entertainment manager beau, David Gardner.
Liv — whose parents are rocker Steven Tyler and model Bebe Buell — was married to her first husband, Royston, from 2003 - 2008 and they welcomed Milo on Dec. 14, 2004.
