Whitney Port is not a fame-whore like Heidi Montag.

On The Hills, she doesn't even allow MTV to film her personal life.

She's a class act and the last person we'd expect to be writing this about.

But thanks to a loose dress and just the right angle, a member of the celeb gossip media got some compromising shots of Whitney dining at Ivy...

An unexpected Whitney Port nipple slip photo has surfaced recently.

We have to say, regardless of this photo, that Whitney Port is gorgeous. She and Lauren Conrad are such natural beauties - unlike some stars!

More (uncensored) pics of Whit can be found here.
