is ringing in the New Year with some new ink!

The pop starlet posted two snapshots on Instagram on Wednesday, showing off her new foot tattoo - a smiley face.

"stick+poke," the "Timber" singer wrote, along with a pic of a tattoo artist working on her new ink.

This is the blonde beauty's seventh tattoo. She has one that says "suck it" inside her lip, "yeah" on her foot, a dollar sign on her hand, a cross on her wrist, an anchor on her wrist and a skull and crossbones in the same place.

While a smiley face is pretty innocent, the songstress revealed on "Conan" that she got her lip tattoo as a message to her haters.
