Dwayne “The Rock” Johnson and Conor McGregor have been gushing over each other on Instagram.

Johnson, renowned for roles in hit movies like “Moana” and “Jumanji: Welcome to the Jungle,” watched “Conor McGregor: Notorious” – the documentary that detailed the Irishman’s extraordinary rise to the top of the combat sports world.

The filmmakers behind “Notorious” followed McGregor over the course of four years – from the fighter’s humble beginnings claiming benefits in Ireland, to his unprecedented success in mixed martial arts where he became a two-weight world champion in UFC.

For Johnson, the documentary delivered a stunning knockout and he told his 106 million followers on Instagram that the movie provides "great insight into the DNA of this successful and smart business man."

Johnson said: "Best part of his success, is when you strip it all away - it will always come down to being the hardest worker in the room. Those roots never go away."

Johnson added: "Solid doc. Well done brother."

It did not take long for McGregor to notice the feedback.

The Irishman said: "Thank you Rock! Your work ethic is inspiring to me and I appreciate these words very much!"

McGregor signed off by saying "big respect my Uce," which is Samoan slang for brother.

McGregor took a hiatus from UFC so he could challenge Floyd Mayweather to a boxing rules contest in 2017 - a bout he lost in the 10th round.

He was due to return to a UFC octagon this year but talk of a comeback bout has been postponed as McGregor is due to appear in a New York City court on June 14.

He faces assault and mischief charges for allegedly throwing a metal trolley through the window of a bus carrying UFC athletes and employees.
