It's Neville Longbottom like you, or J.K. Rowling, have never seen him before.

Matthew Lewis, the actor who played Longbottom in the Harry Potter franchise, has undergone quite a transformation since the films came to an end, and attained quite a following because of it.

Lewis stripped off for the cover and spread in Attitude's 'Swimwear and Underwear Special', with the shots making their way onto the web today and unwillingly making their to Rowling's eyes. It's not so much that she was displeased as she was unprepared to see one of cinematic-own like this.

Hence this tweet to Lewis.

Which then led to this exchange, which will warm the hearts of any Potter fans.

Rowling is like the Irish mammy the Harry Potter kids never knew they had.
