Showing off their strong relationship, Naomi Watts and Live Schreiber were spotted in a passionate embrace in a Saint Tropez parking lot on Sunday afternoon (July 15).

The 43-year-old actress picked up some fresh baguettes with her beau and their son Alexander before hopping on a plane to continue filming her newest movie.

The Oliver Hirschbiegel directed “Diana,” formerly known as “Caught In Flight,” focuses on Princess Diana’s relationship with heart surgeon Dr. Hasnat Khan, played by British actor Naveen Andrews and stars Miss Watts as the princess herself.

“She is a part of our history, an incredible woman and fascinating but a tragic ending,” the “King Kong” actress said while filming scenes for the film.

"Diana" is due to hit theaters in February 2013.
