Somebody give Matthew Lewis a jacket! Or, you know, don't.
Because we can't stop staring at the Harry Potter alum's hot, muscular body in the new shirtless pic he posted on Wednesday on Instagram, taken at a photo shoot for Attitude, which dubs itself "the U.K.'s best-selling gay magazine."
"Bit cold in the studio today..." wrote Lewis, who appears dressed in nothing but gray Hugo Boss pants and lace-up boots as he hugs his perfectly sculpted biceps and gives a cute, teasing look. "attitudemag #photoshoot."
The 25-year-old actor, who played Neville Longbottom in all eight films (no, really), had also showcased his shirtless body in an ALS Ice Bucket challenge video posted during the viral celebrity campaign last summer and has also shared a slew of other hot selfies on his Instagram page, which he made public in March because he is a generous and caring soul.
Lewis, who wore a fat suit sometimes while playing Longbottom in the Harry Potter films, also showcases his hot bod in the BBC series Bluestone 42, which is about a U.K. military bomb disposal unit in Afghanistan.
The show is half drama, half comedy, and features plenty of hijinks.
