Kevin Costner celebrated his 70th birthday on Saturday, Jan. 18, by sharing a throwback photograph of himself from his childhood on Instagram.

The Yellowstone star was a young boy in the resurfaced snapshot, which he posted on Instagram on Saturday, Jan. 18. The picture showed Costner flashing a big smile at the camera while dressed up as a cowboy, complete with a cowboy hat on his head and a holster on his hip.

Costner, still hoping to film the last two chapters of his ‘Horizon’ film series, also toasted to ‘another year of keeping our sights set on our dreams.’
