You`d never know it was a cold night in London by the looks of Jennifer Aniston and `Bounty Hunter` co-star Gerard Butler.

Between Aniston`s sizzling mini-dress and her interaction with Butler, it was positively red hot on the red carpet for the London premiere of the comedy.

The couple`s playful interaction did little to dispel the persistent reports that the two were more than co-stars after the cameras stopped rolling. While others argued that the tactile red carpet display was done for publicity sake or for warmth in the cool evening, many British papers seemed to smell romance.

In its headline, Britain`s Sun newspaper asked, "More than Friend`s, Jennifer?"

The Sun quoted Butler talking about the two`s "perfect chemistry."

"The best thing about this movie is that the two of us got to be together," he said.

The headline for the Daily Express stated: "Jennifer Aniston fan flames of romance with Gerard Butler."

The Bounty Hunter opens on March 19.
