Megan Fox might be another year older … but don’t expect her to stop living on the edge anytime soon – because she says she’s chasing anything that can hurt her.

The actress shared photos from a steamy photo shoot … in which she wears a low-cut brown top and tiny black shorts.

Usually, Fox wears a winning smile, too … but not in this case — because her mouth is full with what appears to be a lit match.

She captioned the literal flaming hot snaps, “i desire the things which will destroy me in the end” … adding a little context to the fire hazard.

Fox is clearly living on the edge as she turns 40 years old … a milestone birthday she’s celebrating without Machine Gun Kelly — with whom she recently had a falling out.

Remember … Kelly was trying to tell her how sexy she was after she posted some hot snaps online — but she didn’t want to hear it and ended up blocking him.
