Katy Perry reveals matching tattoo with Russell Brand as she livens up car launch in exceedingly tight PVC outfit

Russell Brand has made a career out of being outrageous.

And after dating the British actor for nine months, it appears his girlfriend is beginning to show his influence.

Previously a fan of girly prom dresses, Katy Perry now favours ever more kinky skintight PVC.

And she and Russell, set to wed later this year, have a permanent reminder of their love - matching tattoos.

New tattoo: Katy Perry showed off the inking on the inside of her right arm as she performed on the hood of a Volkswagen Jetta in New York's Times Square yesterday

Singer Katy revealed her Sanskrit inking as she performed at the launch of the Volkswagen 2011Jetta yesterday.

It was in an identical position - the inside of her right arm - to Russell's, which he showed off on the front cover of this month's Rolling Stone.

Both their tattoos read Anuugacchati Pravaha, meaning Go With The Flow.

Katy already has a tattoo of a strawberry on her ankle, and one saying Jesus on her wrist.

She flashed her discreet new inking as she performed her song California Gurls on top of the car in Times Square.
