PHOTOS: How time has "flown" for the world's most famous artists

Comparing photos is one of the easiest ways to understand the effect of time.

And this is best seen in an incredible collection of photos showing how time flies, created by Photoshop master Ard Gelinck.

He shares photos of celebrities posing with "themselves" at a younger age.

The photos show that time does not stop for anyone, no matter how famous or influential you are.

Gelinck's glamorous creations have also been re-delivered by some of the stars he has included in the collection such as Madonna, Robbie Williams, Sylvester Stallone, etc.
