Smith now has over 184,000 followers on Instagram, where he posts pictures from their adventures, while also adding in his bio that he is "a professional idiot".

In the above video, you can see Ross and his awesome grandmother faceswapping with each other and using a host of other Snapchat filters.

"I look so young" his gradma says when they faceswap, before Smith quips: "And I look like The Great Depression".

He also pranks the 90-year-old by telling her that he may start selling crack, but she replies claiming she might buy some from him if it's for medicinal purposes.

Among the other hilarious things he does with his grandmother is buy her pop for Christmas, tell her she looks like a traffic cone and gives her pre-workout and lets her loose on a cross trainer.

Watch the video above for some more of the funny moments between them.
