"The new relationship between your new prime minister and our president ... it's going to be sensational," Johnson said, according to the BBC. "Their leadership has a lot in common. Both have their own style but similarities — a clear vision of what they want to accomplish."

Johnson added that there would likely be "bumps in the road," but touted the history of the two countries working together and added that his job was to work on "things we agree on."

"We're going to have bumps in the road, no question, but we are two great countries," Johnson told the BBC.

"If we look forward optimistically between our two countries, we're going to lift all the people in this country ... to independence and all the things you voted for in the [Brexit] referendum."
