Maroon 5 singer Adam Levine has unveiled a big new tattoo on his back.

The coach of "The Voice" shared with his 4.6 million fans on Instagram on Sunday, a picture of his back getting inked by tattoo artist Bryan Randolph, reports aceshowbiz.com.

Randolph inked a number of images on Levine's back. At the center of his back is an image of a long-haired mermaid showing a skull.

In the black-and-white picture, the tattoo artist was drawing another tattoo on Levine's lower back.

The new tattoo joined an existing tattoo of a woman on the left and a "Frankie God" tattoo on the opposite side.

Alongside the picture, the "Animals" singer wrote: "If you ever want a tattoo and you don't get it from @bryanrandolph...you're nuts. He's the DUDE."

Posting similar picture on her Instagram page, Levine's wife Behati Prinsloo captioned it: "House call @bryanrandolph."
