The 42-year-old reality star married wife Vanessa back in 2011, and the couple has since welcomed two children together. Three-year-old Camden John looks handsome in the photo in a black tee and blue shorts, while 1-year-old Brooklyn Elisabeth is a total daddy’s girl in a white dress.

#SundayFunday a rare moment of sibling happiness! All it took was a ranch with ponies, birthday cake, bandanas, face paint and a saddle riding barrel. Haha!!!
