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.

While others argued that the tactile red carpet display was done for publicity's sake or for warmth in the cool evening, many British papers seemed to smell romance.
