BB1 is a must-watch! I got through it relatively quickly since the episodes are so short yet they're so good at the same time <3333 I'd recommend pretty much any from that list except TAR 27 and CBB10.
If you haven't seen Flavor of Love or Charm School then I'd definitely say make that your #1 priority. Probably my 2 favourite seasons of all time in reality tv history
I'm about to watch I Love Money, which is another VH1 reality competition with All Stars from their shows!
