Jack BlackJack BlackThe bleach bottle that is...

It seems this celeb has been thinking that blondes have more fun.

... FYI this is a universal truth.

But after this blokey's transformation, can you even tell who he is?

It took us a moment of squinting.

This latest blonde bombshell is none other than Jack Black.

Cripes, his platinum crop makes him look everso different.

... Also note that he's minus the upper-lip warmer he often sports.

But don't think he's out on a limb by taking the peroxide plunge.

Others have done likewise, while some have flip-reversed it and changed from light to dark.
