Earlier this week, British tabloids reported that Brad Pitt's "drinking and pot smoking" could lead to a split from girlfriend of five years Angelina Jolie.

Samm Levine, Pitt's costar in Quentin Tarantino's Inglourious Basterds, admits the actor, 46, likes to throw back a few.

"Oh, he's a fine drinking buddy," Levine, 27, told at the Sundance Film Festival Wednesday while promoting his new film Drones. "Between Brad and Quentin, I would die of alcohol poisoning on day two if I had to keep up with those guys!"

Joking aside, he said it was "great" working with Pitt.

"Brad and I had a great talk about accents because I loved the accent that he was doing, and we had a wonderful fun time," Levine said. "I began poking fun of Jon Voight's accent from Anaconda."

He didn't realize until later that Voight, 71, was Jolie's father.

"So we had a great long conversation about that, and then I walked away, and thought, 'Jon Voight is kinda like his father, isn't he?'" Levine told Us. "That probably wasn't the best person to talk about!"

Luckily, "it turned out not to be a big deal," Levine told Us.

Levine said Pitt probably isn't sweating those split rumors, either.

"Brad's just about the coolest guy," he said. "Everything rolls right off his back."
