Bradley Cooper is very happily dating Renee Zellweger, and many can't wait to see when the 'Limitless' actor will propose to his longtime girlfriend. But is the actor afraid of marriage after his first one failed after just four short months? He stopped by Howard Stern's Sirius XM radio show this morning and discussed just that.

Cooper married 'Blue Bloods' actress Jennifer Esposito in December 2006; Esposito filed for divorce just four months later in May 2007.

"It was just something that happened," Cooper said about his quick marriage [via UsMagazine.com]. "The good thing is, we both realized it ... Sometimes you just realize it. It just wasn't right. It's interesting ... things happen!"

When the talk show host asked if it turned him off of marriage for good, Cooper said that wasn't true. "Making any declarative statement [like that] is a joke," he said with a chuckle.
