Who knows all of Bradley Cooper's secrets?

Actors working together tend to bond, and Alessandro Nivola says that's exactly what happened between him and his Elephant Man co-star Bradley Cooper.

They got tight. They hung out. And the rumors began.

“We were together at the French Open and now everyone thinks we’re a couple,” joked Nivola.

They've shared things.

“We share a dressing room. I know all his secrets. I’m not revealing any of them.”

As for Nivola's mustache...

“I’m waiting for the Magnum, P.I. reunion. Why haven’t they come calling?”
