And he enjoyed it.

“Saturday night doc viewing NOTORIOUS,” he posted on Instagram. “Great insight into the DNA of this successful and smart business man. 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. Solid doc. Well done brother.”

McGregor, currently sidelined awaiting a trial for his involvement in the incident in New Jersey earlier this year, responded, writing “Thank you Rock! Your work ethic is inspiring to me and I appreciate these words very much. Big respect my Uce.”
