The 68-year-old producer and the American Idol alum were spotted taking a stroll in Paris, France on Tuesday, hugging, kissing and taking pics of one another.
The 33-year-old Scorpio star wore navy leggings, a black jacket and beanie and tennis shoes. She wrapped her arms around Foster, who kept things casual in jeans, a black coat and aviators with one of the lens missing.
This isn't the first time cameras have caught the twosome packing on the PDA. Earlier this month, McPhee and Foster were spotted kissing after lunch at E Baldi in Beverly Hills, California.
