Unfortunately, her frenemy Lady Gaga did the same thing a couple of years ago so it's not a totally original idea, but don't tell Kel because she seems happy with the latest addition to her ink collection.
The 29-year-old posted a pic of the work in progress on her Twitter page with the caption "sorry mum and dad but I love it." The cool thing is that if she ever does get tired of it, she can totally just grow her hair out and it'll be like it never even happened.
She didn't explain the meaning behind getting the word "Stories..." scrolled on the side of her skull, but our guess is that it might be a testament to everything she's been through and the stories she's got stored up there. Or...not? Who knows.
Would you ever get a tattoo on your head?
