Mariah Carey Flaunts Fantastic Body And Rock Hard Abs In Red Bikini (PHOTOS, VIDEO)

Of all of the celebrities we've recently seen flaunting their bikini bodies on beaches, Mariah Carey's may be the best.

The 42-year-old singer and 'American Idol' judge shared this sexy photo of her beach bod with fans on Twitter. The hot momma of twins — Moroccan and Monroe — took the snap in Australia (where she's currently on tour) during a day of beach-frolicking with her family.

Her rock-hard abs, her perky breasts, her sexy hips — it looks like all of her hard work eating healthy (thanks to Jenny Craig) and working out has paid off.
