Ever wonder what Katy Perry, Leonardo DiCaprio or Hugh Grant might look like in their golden years?

Now we know, thanks to the magic of the makeup chair.

Perry, 27, was transformed into what she describes as the "grandma" version of herself in her new music video for "The One That Got Away."

DiCaprio, 37, put on 40 years for J. Edgar, the biopic of the FBI's founding director, while new dad Hugh Grant, 51, tacked on decades thanks to the special-effects makeup he sports on the German set of his sci-fi flick Cloud Atlas.
