isn't one for subtlety is she?

The outrageous, glitter-covered singer revealed she got a new tattoo in an unlikely spot last night: Her lip!

She shared a photo of her "new tatt" on Twitter after getting the word "Suck It" inked to her lower lip at Alchemy Tattoo in Silver Lake.

Sure, it's crazy ... but not that unexpected with Ke$ha. Plus, lip tattoos fade quickly, so she may not be sporting the new art all that long.

The 25-year-old also has an anchor, skull and crossbones, cross, dollar sign and the word "YEAH" on other parts of her body.
