The handsome Silver Linings Playbook actor sat down with Hangover Part 3 costars Ed Helms and Zach Galifianakis at the Las Vegas junket for the upcoming comedy, where E! News couldn't help but question whether Bradley's ‘tude has changed since the very first Hangover flick.
"We can't say or that giant guy off-camera will beat us up," Ed Helms confesses as Cooper quietly laughs.
"We're afraid to talk,"Galifianakis dead-pans.
Eventually, Helms provides an honest response, praising his costar for his down-to-Earth demeanor.
"Honestly, it's really annoying how little Bradley has changed," he says. "You really should be more of a diva," he tells his pal. "You can pull it off now! You have an Oscar nomination, come on."
And suddenly, Cooper just became that much sexier.
The Hangover Part III hits theaters May 23.
