The superstar poses on a balcony behind a backdrop of palm trees, while holding her hands up to her hair and wearing a revealing two piece covered with a sarong.
Captioning the photo, she said: "Working in my most favourite environment clearly having a bad hair day.. Haaaaaa."
Mariah, there's no such thing as a bad hair day for you!
Mariah, who is mum to three-year-old twins Monroe and Moroccan, is expected to release her new studio album The Art of Letting Go in the Spring. It will be a follow-up to her last album, Memoirs of an Imperfect Angel, which was released in 2009.
The 'Hero' singer also recently announced that she will drop a new single on Valentine's Day. We can't wait!
But Mariah is proving that music is not her only forte, as she revealed plans last week to release a book with her husband Nick Cannon.
The couple will release the children's picture book later this year, which will be based on Monroe and Moroccan! The book, which will be called Roc and Roe's Twelve Days of Christmas, is set to be a modern twist on a classic tale.
In a statement on Nick's website, they said: "We are so excited to work with the Scholastic team on our Roc and Roe picture book and we can't wait until this holiday season!"
