Yellowstone star Mo Brings Plenty's nephew Cole Brings Plenty has been missing since Easter. 

His costar Cole Hauser - who plays tough guy Rip on the popular Kevin Costner-led series about Montana ranchers - shared the news on Tuesday.

Mo's nephew was last seen driving his white Ford Explorer in Kansas City, Missouri, on Sunday.

Hauser called Mo his 'good friend' in his Instagram caption as he said Cole Brings Plenty has not been heard from in two days.

'He was last seen on Easter evening in Kansas City. If you have any information on his whereabouts please contact the below or your local police,' added Hauser.

Cole Brings Plenty also starred on two episodes of the Yellowstone spinoff 1923 as Pete Plenty Clouds. He worked as a model too.

Earlier this year Cole Brings Plenty was on the series The Tall Tales Of Jim Bridger and Into The Wild Frontier. 

His Hollywood career was heating up as he was following in his uncle's footsteps. 

Hauser also shared a flier which included a photo of Cole Brings Plenty. He has long braids like his uncle Mo, and is 5ft10in and 150lbs.

The poster also asks that people with information contact @bellanringsplenty. 

Cole Brings Plenty was last seen leaving out of Lawrence Kansas South on 59 in Kansas City. U.S. Route 59 is a north–south United States highway.

A missing person report has already been filed by the family, Hauser added. 

Mo Brings Plenty, 54, is an Oglala Lakota television, film, and stage actor, as well as a traditional drummer and singer. 

He is best known for his portrayal as 'Mo' - the driver of Rainwater - on the series Yellowstone. 

He is also the show's Native affairs coordinator, working with tribes to ensure that the Native languages and cultures are represented correctly.  

The actor was born on the Pine Ridge Reservation in South Dakota. He is a direct descendant of Brings Plenty, an Oglala Lakota warrior who fought in the Battle of Little Big Horn.

Mo has also had roles in Hidalgo, Thunderheart, Pirates of the Caribbean, Cowboys & Aliens and Jurassic World Dominion. He can also be seen in several of the documentaries for The History Channel.
