After thanking his fans for wishing him a happy 70th birthday, Costner addressed the baby photo, writing, “If you can believe it, this is me. I was chasing the cowboy life just about as soon as I could walk, and here I am doing it still. Here’s to another year of keeping our sights set on our dreams.”

Several of the Dances with Wolves actor’s fans praised the “Simply A D O R A B L E❤️” photo, with one observing, “What a beautiful cowboy baby… you were looking pretty dear.”

“Happy Birthday Kevin. You’re my favourite cowboy. Modern or olden times,” another fan commented.

New birthday wishes echoed throughout the post’s comment section, with one Instagram user writing, “Such a Cute pic!! Happiest of Birthdays to you ! 🎉🎂❤️🎈🤠,” while another wrote, “Happy birthday to the best actor on planet earth!”

Costner’s country rock band, Modern West, also left a comment on his baby photo, dubbing him a “Cowboy from day one.” The band shared a separate tribute to the actor on its official Instagram account that featured a video of the Horizon: An American Saga director singing and playing guitar.

“Birthday champagne is in order for @kevincostner! 🥂,” the band wrote. “God decided to dole out a few extra heaps of talent on January 18th 1955. We’re lucky you share that talent with us and with the world!”
