Discussing his rumoured romance with the former Friends star, Cooper maintained that they are just friends.
People quotes the actor as saying: "She's a friend of mine. Simply, simply, just a friend."
He added: "In America, it's not like it is here. She's someone who is super, super known. Famous. If someone says 'hello' to her, it's given that he's fallen in love with her. So, no. No. She's a very, very interesting woman, but she's simply a friend.
"We made a film together but we didn't have any scenes together. I got hired in at the beginning of the casting, and my part was solely with Scarlett Johansson and Jennifer Connelly. Which isn't bad at all."
Earlier this month, Cooper confirmed that he will star in the upcoming A-Team movie.
