Big Brother 26 has been a bit of a disaster in the NSFW realm - not because we didn't get a hot cast, but because CBS/Paramount made the terrible decision to do away with the ability to flash back on feeds. So any nudity moments can't be relived unless someone manually records feeds, and thankfully our great friends on the Big Brother NSFW are coming through so we don't miss out completely.
What we have is Rubina casually getting out of the shower, and with no one else around, adjusting her towel without realizing she was giving the camera a view. While not the full-frontal views we've seen from past houseguests, it was quite an eyeful and possibly even a quick nipple glimpse.
