The 'Tik Tok' hitmaker showed off her new inking - the words "Suck it" tattooed on the inside of her bottom lip - via Instagram on Wednesday, reported Us magazine.
Never one to pass up an opportunity to show off her statement-making and daring style, the 25-year-old singer has tweeted pics of crazy antics like gluing gold studs to her head and using an eyeliner pencil as a lipstick.
"I embrace the imperfections and celebrate them," she has said earlier.
Then, adding some colour to her outrageous lifestyle, she admitted, "Sometimes I have parties at my house in Nashville and it's clothing-optional, and we just body-paint each other and run around."
