Sadly, I think it is :o(

There hasn't been a comment from her people about it yet, however the pictures on pretty much every blog and celebrity news website appear legitimate.

I just hope that if it is it doesn't affect her relationship with Sebastian Stan at all, and won't give her a bad reputation. I don't think it would ruin her career, but I hope that it won't enhance it in the wrong way.
She's not Paris Hilton or Kim Kardashian, she actually has a lot of talent and personality and made her name with that.

Apparently it's already available to watch for people with a paid subscription to celebhotline.com, so that kind of confirms it's real.

It was made years ago, though, long before she had any degree of fame... and I'm not going to judge her for it. Plenty of average people take racy photos etc of themselves, it's just unfortunate that Leighton had hers thrown into the public just because she went on to find fame.

Just to calm everyones nerves, no need to worry! It doesnt exist! In a magazine she recentally appeared in she spilled that it doesnt exist. It wont hurt her acting or anything!

I sure hope so...;p
