Actress Halle Berry has been spotted making out with her 'Dark Tide' co-star Olivier Martinez in his hometown of Paris.

The two have been seen smooching and exploring the city, embracing a Hollywood-style romance straight out of a movie.

"It was the classic 'I'm going to kiss you here in a dark corner' move," People magazine quoted an onlooker as saying of their romantic romp.

"And she was waiting to be kissed," the source added.

The duo spent Sunday afternoon combing through the streets arm in arm, taking in a pit stop at the Paris flea market.

"They had their arms around each other as they walked," the onlooker said.

"They were both smiling and laughing. Their body language was very flirtatious. They definitely seemed like a couple - absolutely looked like more than friends," the onlooker added.

The two sped off on Martinez's motorcycle before dining at the intimate Casa Bini restaurant.

After dinner, Martinez led Berry on a cozy back-streets tour of the St. Germain district at dusk, including Place Saint-Sulpice and its fountain.

En route to his Paris pad, the couple stopped along a narrow street and kissed in a doorway for two minutes, an onlooker said. (ANI)
