[Britney] Photoshop or not?

I was talking with my friend about this picture of Britney

He supported Photoshop since it was her arm in the photo was great, I thought that it was strange that although achasse, recalls much the arm of Madonna

What you think, this is photoshop?

Yes, it is. It looks very fake. I take a class that teaches me how to spot phony photos, and this one has every detail.

ooh! I don't know! I doubt it's fake, though. She's a hottie... works out, right?
You didn't define "Photoshop".

Almost all photographers will Image%26gt;Adjust%26gt;Curves (or the equivalent) and often crop the photo. Yes, of course this was done.

Some photographers will apply a brushstroke/distort/sketch filter that make it look like it was drawn by hand, or like you're looking through glass. But this will never result in someone having three arms, or a friend being removed from the photo. One of these filters were probably used here, though it's hard to be sure because the most obvious issues in the photo probably came from the image being scanned in from a magazine.

What many people casually mean by "photoshop" is the addition or removal of arms/people/etc. Do you suspect that was done here? What part of the image do you suspect this was done on? The image is of low enough quality that it's difficult to analyze every part of the photo for these sorts of modifications.
