Tik Tok hitmaker Kesha has joined forces with Humane Society International to star in a public service announcement to support the introduction of the Humane Cosmetics Act ­legislation.

The legislation will phase out animal testing for cosmetics, as well as ban the sale of newly animal-tested cosmetics. Shot by celebrity photographer Robert Sebree, the video sees Kesha getting ready for a night out, using various cosmetics. Surrounded by rescued bunnies, the campaign ad then asks consumers 'Does animal testing lurk behind your cosmetics?'.
