Unofficial and unconfirmed at the moment, but the French celebrity magazine 'Public', briefly had a topless picture of Emma Watson on holiday on the digital version of their mag, before removing the item.
This picture, grabbed before the magazine pulled it, has been AI upscaled. Looks pretty legit to me.
