The Big Brother 20 cast has only been known for a matter of hours and lo and behold, we already have nudity.Every year the legion of die-hard Big Brother fans are busy hunting down any sort of controversial info. on the new houseguests; in some cases like last year with Christmas Abbot, we got to see some sexy naked photos of her before she even entered the house. This year, we have a true rarity as it has been discovered that BB20 houseguest Rachel Swindler actually did a nude scene in the series "Graves."In the scene, Rachel plays an escort at a wild party and she's completely topless with her boobs in plain view. We don't want to get our hopes up too high but the scene does make us wish a party in the Big Brother house got to this level!So if Rachel already gladly showed her boobs for a TV show, she should have no problem having cameras on her while she showers in the Big Brother 20 house, right? We can only hope. The hype is already huge for Big Brother 20 and Rachel is already on our NSFW radar. While we all hope she delivers tons of hot content during the Big Brother season, here is Rachel Swindler topless in "Graves" to hold you over:
