It is the beauty secret that has had music fans across the world stumped. But now the secret is out, and it has been revealed how Adele always achieves her flawless cat eye liner look. The Hello singer's makeup artist, Michael Ashton, has shared the award-winning singer's style secrets.

"Product cocktailing is key to achieving the intensity and opaqueness of the eyeliner," he told The Cut. "I always start by outlining the shape of the liner, working from the inner to outer corner of the eye with a black gel liner.

"I then work the product right into the root of the lashes and then build thickness gradually. Once I'm finished creating the desired shape, I use a waterproof liquid liner with a precision tip to intensify and refine the line, finishing by winging the end of the liner last."
