Carey vacations with close friend Brett Ratner in France
The pair were photographed waking arm-in-arm through town with another female friend while shopping, reported Us magazine.
Carey, 45, wore a bikini while Ratner went casual in a T-shirt and jeans.
Both have denied any sort of romantic relationship, but they have been spending significantly more time together. Last week, they went out for a dinner date with Courtney Love.
