Mariah Carey flaunts EXTREME cleavage in studded bra in bathtub snap
In the first snap, the 46-year-old popstar celebrated the romantic holiday with a glass of bubbly as she donned a slinky bikini for a dip in the tub with her backing dancer boyfriend Bryan Tanaka, 33.
The couple definitely looked to be enjoying their first Valentine's Day together as she rested her hand on Bryan's muscly arm in the steamy upload.
In another two posts to her Instagram, she opted for an eye-popping silver spiky bra that showcased extreme cleavage as she rolled around in yet another bathtub, this time surrounded by balloons, streamers and sweets.
