Mariah Carey flaunts a close-up shot of her huge cleavage to mark the start of her holiday

Mariah Carey has NEVER been shy about showing off her figure.
So what better way for her to announce that she's taking a much-needed holiday than by posing for a close-up shot of her boobs - in a lacy bra?
The Hero hitmaker finished up her Las Vegas residency last Friday and was quick to jet off to Greece for some R'n'R.

Sharing the news with her fans, she uploaded several sexy snaps of herself to Instagram on Tuesday.
Celebrating her break, Mariah posed in a very revealing red bra that featured some black lace detailing and looked like it struggled to contain her ample assets.
She teamed it with some fishnet stockings and a fuschia silk chemise that draped over her shoulders.
She captioned the first of the three snaps: "Vacation begins!"

One image sees her lying back on a white pillow with her long hair spread out around her and with her hands perched just above her chest.
In the second snapshot, she's sitting up to look at the camera and writes: "Greetings #Greece."
In the third photo, a sleepy-looking Mariah grasps the chemise around her upper thigh and captions the pic: "Goodnight."
