Jennifer Lawrence and Bradley Cooper have done some pretty steamy scenes together on the big screen–so much so that many have wondered why the two have never hooked up in real life.

Or have they?

That’s the question Howard Stern asked Bradley Cooper when he was a guest on Stern’s Sirius XM satellite radio show on Wednesday.

“When are you two gonna have sex?” Stern asked Cooper of Jennifer Lawrence. “Everyone is waiting for that.”

“Never,” he replied. “It’s just not the way we are together.”

Bradley Cooper and Jennifer Lawrence starred opposite one another in Silver Linings Playbook, Serena, and American Hustle. They will star in Joy, too, which is due out on Christmas Day.

Howard Stern’s question wasn’t all that unfamiliar to Bradley Cooper. He and Jennifer Lawrence have both been asked the question a number of times.

At the 2013 Academy Awards, Cooper was asked if he and Jennifer Lawrence were dating.

“Oh my God. That’s very funny,” Cooper said. “No, my God, no.”

“No, no, no, no, no, not even close,” he continued. “First of all, I could be her father. No, I’m kidding. But no, not even close.”

Jennifer Lawrence maintains the two get along so well and work so famously together because they’ve never had sex. She said this past March during a screening of Serena that their secret was “no sex.”

Lots of fans of Bradley Cooper and Jennifer Lawrence are no doubt sighing big, disappointed sighs. They have likely held out hope that the couple who is so convincingly sexy together on screen won’t ever become a couple in real life.

Don’t you love seeing Bradley Cooper and Jennifer Lawrence play opposite each other in the movies? Are you among those who secretly wished they’d start dating for real?
