"Animal" pop star Ke$ha showed us her stripes -- and a lot more -- on Instagram last night.
The singer shared a scantily clad selfie, in which she's stripped down to a nude bra and tiger mask, before her show at Paradiso in Amsterdam. Her photo caption read, "backstage. feelin like a saber tooth. ti. ger."
It wouldn't be Ke$ha without some rock 'n' roll antics: She also flipped fans the double bird, garnering 24,000 likes. Fierce.
