Photo: AnnaLynne McCord’s Twitter Breast Slip-Up

Before realizing she exposed a bit too much skin for a fan, AnnaLynne McCord accidentally posted a topless picture of herself online.

But once the “90210” hottie realized that one her breast was showing, she quickly removed the pic, re-cropped it and replaced it.

Making no mention of the slip-up, McCord tweeted, “This is for you @meganraee. You rock! Xxx.”

Sounds like AnnaLynne wanted to cover her tracks, however, as her fan later re-tweeted, "Yes its gone! I wasn't Sure if you noticed it when you posted ... that's definitely a great picture!"
