BB13 Nude: Rachel's Boob Falls Out in the Backyard

We are over halfway through season 13 of Big Brother, and the nudity this season has been at an all time low.  Most likely that has to do with half of the house being people who have already been in the house, and know to be extra careful of the cameras being some have been caught naked before.  That's all well and good, but the good old wardrobe malfunction can still deliver some unexpected Big Brother nudity.

With Rachel flaunting her big fake boobs around, it was only a matter of time before they fell out.  While in the backyard talking to Jeff and Jordan, Rachel was adjusting her bikini top and it slipped out of her hand exposing her full boob.  Unfortunately, the cameras were only on Rachel from the side, but it was definitely apparent that her whole breast was exposed.  Check out the pics of Rachel's boob show moment below:
