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. Seems Fox is all about toxicity as she celebrates the big 4-0 ... but not when it comes to her ex!
