Now this is a bromance.
And to fully capture the moment, the duo snapped a selfie while they were sitting in the stands.
Andy Murray won the famed tennis tournament, ending a long drought for the Brits, when he became the first British man to win Wimbledon in 77 years.
"I understand how much everyone wanted to see a British winner at Wimbledon so I hope you enjoyed it," Murray told the crowd after the match, according to USA Today. "I tried my best."
And Cooper and Butler weren't the only celebs cheering on the Brit's big win.
"Oh my God. What a match, what a player. Inspiring a Nation. .Andy Murray!! Ya Beauty," McGregor wrote.
Piers Morgan also chimed in tweeting, "To all the #Murray haters: Eat. That. #WIMBLEDONCHAMPION"
