The articles talk about the director and crew behind the video and they used stills from the pre-final product, of course they wouldn't talk about retouching.

Here's a comparision, btw:

I'm waiting for those raw vocals...

But she's better without the retouche, cause she has NO hips on the MV, they want to make us believe she's a toothpick, we know she has some meat, here and there.

Everyone is altered in videos. Just like how everyone is altered in photo shoots. She's not the only artist ever to get photo shopped.

This isn't directed towards you or anything, but I feel like whenever there's a photo shopping story in the press somehow Britney is always tied into it. It's ridiculous. She's a beautiful woman, and works hard to maintain a healthy body.

But she still looks great

PS: everyone is slightly altered in music videos

LOL but these don't look much different at all though.

Barely edited

I believe her body was retouched. Look at her body by the time of the shooting, she looks way bulkier than in the video.
