"Harry Potter" scribe J.K. Rowling had plenty to say on Twitter Thursday in reaction to actor Matthew Lewis' revealing photo spread in Attitude magazine.

Lewis, who played Neville Longbottom in the "Potter" films, appears shirtless on the cover and bares even more in a nearly nude spread inside.

"Not as bad as watching Dan [Radcliffe] in 'Equus,' but close. Warn me next time, for God's sake," the author tweeted.

Lewis, 25, replied: "Well, this is awkward. Sorry, Jo."

Rowling, 49, then posted: "I will always support you whatever you want to do, Matthew. Now go put some clothes on."

The actor's buff physique was part of his transformation for his upcoming film "Me Before You," in which he'll play a triathlete and personal trainer. Lewis said he's adjusted his diet to get into the mindset of the character and transform his body.
