To the casual observer, Brad Pitt and the woman with whom he was strolling through the streets of romantic Costiera Amalfi, Italy, on Oct. 30, looked like head-over-heels lovers, perhaps even newlyweds.

“There really seemed to be a chemistry between them,” said one onlooker. Unfortunately for Jennifer Aniston, she wasn’t the woman on her husband’s arm — it was Angelina Jolie. Star has never-before-seen photos showing the movie stars as they tenderly touched in the small, quaint seaside resort town near Naples.

The pictures show the Mr. and Mrs. Smith co-stars getting increasingly cozy after the movie cameras stopped rolling on the film they were shooting. The pair, according to witnesses, took a stroll together along the picturesque streets of the village and were “always laughing and joking.”

Brad, 41, and Angelina, 29, were on the exclusive Amalfi coast to shoot scenes for their movie. They stayed at the plush, five-star Hotel Santa Caterina, in separate $1,200-per-night suites, and dined under the moonlight on the hotel’s terrace, overlooking the Mediterranean. One onlooker said: "You wouldn't have thought that Brad had a wife back in America. He and Angelina looked like lovers." Representatives for both the stars have denied that there was any romantic relationship between Brad and Angelina.

Meanwhile, Brad and Jennifer, now on the road to divorce, are no longer even living in the same house — a $13.5-million Beverly Hills mansion that he decorated, but that Jennifer always hated. As of press time, she was living in West Hollywood with her friend and hairdresser, Chris McMillan, the man responsible for giving her the famous “Rachel” haircut.

Brad's family is hoping for a reconciliation between he and his wife, but only time will tell if he and Jen get back together or if he and Angelina become Hollywood's next glamour couple.
