Mariah Carey is certainly living in the lap of luxury as she holidays with her fiance in Saint-Tropez

 Mariah Carey has been making her mark all over the Mediterranean these last few weeks.

 The superstar singer has been on an extended holiday with her billionaire beau and is clearly living in the lap of luxury.

 The mum-of-two was spotted sipping on what appeared to be rose champagne as she hid behind a pair of huge showbiz shades after their travels took them to Saint-Tropez this week.

 Mariah had her ample cleavage on full display in a plunging white dress which also highlighted her killer curves.

 Living up to the diva label, the star was also pictured being followed by a man who was dutifully shielding her from the sun with an umbrella.

 The 46-year-old diva has been dazzling in an array of outfits all week as she wines and dines with her fiance and their pals.
