NEW YORK — Jennifer Aniston and Gerard Butler hit the red carpet Tuesday night for the premiere of their new film, The Bounty Hunter.

While she didn't address romance rumors surrounding the co-stars, Aniston did admit that she and Butler "had a ball" filming the action-comedy, which opens in theaters this weekend.

"We had a great time together, we really did," said Aniston, 41, from the red carpet.

Butler, 40, echoed the fun times during filming, saying Aniston really stepped up when it came to shooting her action scenes.

"She was amazing," he said. "There's a lot of stuff that she hadn't done before, but for her it was nothing."

"The first car chase that we did she was a little bit freaked out, but after that she was loving it," added Butler. She couldn't get enough of it."
