In a brief statement on his social media, the "Yellowstone" actor advised followers to "Don't believe what they say about getting older

Every year that goes by is a blessing, and it just gets better with time. I appreciate the birthday greetings."

"Happy birthday to the most renowned employee and coolest television grandfather a child could possibly have! I'm hoping you get some cake tonight "Merrill composed.

Prior to the Jan. 10 awards, Costner stated in a Twitter video that "We had to pull the kids out of school in Santa Barbara yesterday

." The motorway has flooded twice in the past five years, and last night we were unable to return after getting lost on the wrong side of town.
