It looks like George Clooney won’t be starring alongside Leonardo DiCaprio or Russell Crowe anytime soon. According to the latest December issue of Esquire magazine, the 52-year-old Hollywood heartthrob opened up about his feelings for Tinsletown’s two leading men. And let us just say — Clooney’s disses will definitely leave a sting.

UPDATE: Was George Clooney Just Kidding With His Diss Of Leonardo DiCaprio?

During Clooney’s candid interview, the Gravity star made sure to leave no stone — or should we say ball — unturned as he described his athletic encounter with DiCaprio and his gang of trash-talking friends. “You know, I can play," the Monuments Men star said of his basketball skills. "I'm not great, by any means, but I played high school basketball, and I know I can play. I also know that you don't talk s--t unless you can play.”

The salt-and-pepper-haired actor explained that DiCaprio’s friends talked smack the entire game — even after they lost 11-zip. “We're all like 50 years old, and we beat them three straight: 11–0, 11–0, 11–0. And the discrepancy between their game and how they talked about their game made me think of how important it is to have someone in your life to tell you what's what. I'm not sure if Leo has someone like that."

But Clooney wasn’t as subtle when he took a painful jab at The Gladiator himself. After a feud that began in 2005, the ER actor explained why he couldn’t accept Crowe’s apology for calling him a sellout.

"He picked a fight with me. He started it for no reason at all," Clooney recalled. "He put out this thing saying, ‘George Clooney, Harrison Ford, and Robert De Niro are sellouts.' And I put out a statement saying, ‘He's probably right. And I'm glad he told us, 'cause Bob and Harrison and I were also thinking about starting a band, which would also fall under the heading of bad use of celebrity.' And that's when he really went off on me. ‘Who the f--k does this guy think he is? He's a Frank Sinatra wannabe.' He really went after me. And so I sent him a note going, ‘Dude, the only people who succeed when two famous people are fighting is People magazine. What the f--k is wrong with you?'"

Crowe tried to patch things up with the Ocean's Thirteen star by sending Clooney a disc of his music and a sample of his poetry. "I think he said, 'I was all misquoted,' and I was like, 'Yeah, yeah. Whatever.’”

Turns out this Hollywood star has a dark side, too! Are you surprised to hear what Clooney had to say about DiCaprio and Crowe? Sounds off in the comments section below!
