Despite having opted for a curve-hugging wetsuit, Mariah Carey still managed to flash a little too much as she took a dip in the sea in Sardinia yesterday.
The US hitmaker, who is enjoying an Italian break with her new billionaire beau James Packer, teamed her black and pink all-in-one with a plunging bikini.
The embarrassing incident however came about when the 45-year-old was snapped getting onto a jet-ski during her day at the idyllic beach.
The mother-of-two accidentally flashed her nip-ple after undoing her swimming gear, displaying her ample bust to fellow holidaymakers.
Mariah, who was fortunately wearing a plunging black halterneck underneath, kept her glamourous sunglasses firmly on as she made sandcastles with her four-year-old twins, Monroe and Moroccan.
There was no sign of Australian businessman James, 47, during the group's outing, however Mariah was accompanied by a number of pals.
The singer, who has been single ever since her split from husband Nick Cannon last year, was previously seen looking very happy with her new man in the resort the previous day.
However the stunner still made sure to wish her ex a Happy Father's Day yesterday, by posting an Instagram snap of her little ones holding up two adorable drawings.
She captioned it simply: "Happy Father's Day @nickcannon! Love, Roc and Roe."
Mariah and James first set tongues wagging at the weekend when they were pictured holding hands.
According to Forbes, the man in question is worth a staggering $4.6 billion and is Australia's fourth richest person.
Twice-married James has dated a string of beauties in the past and was most recently linked to Miranda Kerr, following her split from Orlando Bloom.
