The 30-year-old singer, who recently signed up to be a judge on US 'X Factor', is launching the scent which will combine two of her favourite smells in a sophisticated bottle, reported Contactmusic.
"With Fantasy Twist, I wanted to combine two of my favorite fragrances into a sophisticated bottle, giving my fans the power to choose the scent they desire at any given moment," she said.
The fragrance comes in a sphere-shaped bottle that twists in half and turns into two smaller containers in Spears' favourite colours, pink and blue, which enables fans to wear both together or separately.
Midnight Fantasy smells of black cherries, plum and framboise, while Fantasy has a muskier scent with hints of white-chocolate orchid and jasmine petals.
