Yes, that is a Black Widow spider, no it's not photo shopped. Usually the red marking is shaped like an hour glass - but this one being extremely large and fat has a heart shaped marking instead.

Black widow spiders as everyone knows are poisonous, and not at all uncommon in the South East.  You usually don’t find them in houses fortunately, but it isn’t at all uncommon to see them in unheated garages.  Usually they will be under a rock or other debris, but I have seen them nesting 8 feet above the ground in the open – inside of my garage.  Usually you will run across these things in late spring and early summer.

Be careful where you put your hands, and teach children to be careful as well.  If bitten, don’t panic, but seek medical help.  If possible always catch the spider and take it with you (especially if you think you have been bitten by a brown recluse) for positive identification.  However, with it’s distinctive bulbous body and glossy black and red paint job nothing else looks anything like a Black Widow spider.

Usually the red mark will be on the bottom side of the spider and will be shaped somewhat like an hourglass, but as you can see when they get big the markings get stretched out of shape and move around – just like most of those tattoos you see on the young folks nowadays probably will.
