Sorority Sister on Big Brother

So my crazy sorority sister is going to be on this season's Big Brother starting July 8 (next Thursday). I have never watched the show before but I will be watching it now that Rachel is on there -- she has always been entertaining lol She will be easy to spot on TV with her bright red hair. My sorority sister Ashley posted this link on Facebook that talks about Rachel, seems like she is one of the top 6 picks!
