George Clooney, Brad Pitt, Dustin Hoffman and Julia Roberts will pose to raise money for diabetes research in an exhibition at London’s Getty Images Gallery.

Acclaimed photographer Andy Gotts has taken the pictures and has paired them up according to their most memorable collaborations.

Gotts reveals, “The idea was a book of celebrity portraits with a connection between each of the artists.”

So Clooney is paired with Brad Pitt since both of them had starred in “Ocean’s Eleven”.

The exhibition opens at London’s Getty Images Gallery and all proceeds go to diabetes research.
