Showing some love to his British fans, Bradley Cooper showed up at BBC Radio 1 studios in London, England this morning (May 23).

The “Limitless” hunk was in the house for an interview with Zach Galifianakis to promote their brand new movie “The Hangover Part III,” slated to hit theaters Stateside today!

Cooper told press he’s eternally grateful for the success of the franchise- "We really didn't let any day pass without taking stock of what we have because of these movies, and how special our bond is.”

"It really is a once-in-a-lifetime thing and to be able to do a third one and go out knowing it's over, hopefully we're going out on a high note."
