Don't mess with Emma Watson.

The actress reportedly went after a celebrity website after it published photos of her in a sheer top that showed her nipples.

According to TMZ, the offending pics were published by Celeb Jihad and have since been taken down.

According to the gossip site, Watson sent a cease and desist letter after it shared the images that were allegedly snapped by her stylist.

Watson supposedly claimed her stylist gave her the rights to the racy pics.

A rep for Watson did not return FOX411's request for comment.
