It's Katy Perry's tattoo! The 'Part of Me' songstress got this Sanskrit ink with her ex-hubby Russell Brand. It reads 'Anuugacchati Pravaha' which translates to "go with the flow." Very fitting!

Though Perry's marriage to Brand didn't last long (word is, he's having his matching tat removed), this ink will be on her arm forever. But it's not so terrible, Perry will always see her tattoo and remember to keep her cool!
