Brad Pitt and Angelina Jolie might be the world's most gorgeous couple, but their looks have earned them the dishonour of landing at the top of a new list of bad-skinned celebrities.

The MR + MRS SMITH stars have been named the Dermatology Duo by top skin doctor VAIL REESE at his annual Skinnies Awards.

Reese claims the couple aren't quite as clean-cut as they seem. He says, "Brad has acne and acne scars, while Angelina also suffers from acne and she also has moles and a scar on her face.

"She's also covered in tattoos, of course, so that always tops my list."

Dr Reese announces his Skinnies on his website, and every year he finds photos of the stars to back up his blemish boasts.

Others dishonoured on his new list include Golden Globe Awards winners Joaquin Phoenix (Most Striking Scar) and Reese Witherspoon (Boldest Botox Abstinence) and Philip Seymour Hoffman (Pale and Proud Award).

The San Francisco, California, doctor also pokes fun at Katie Holmes (Worst Timing Award) for sporting a cold sore on her top lip as her relationship with Tom Cruise went public.

And he has special praise for the special effects department on the last Harry Potter film, HARRY POTTER + THE GOBLET OF FIRE, for keeping the adolescent stars in the film pimple free.

He says, "They must have used a computer blemish eraser to conceal the cast's pimples. A tremendous job."
