I have no idea who any of those people are apart from Miesha.
Literally no idea.
Edit:
I have researched so that you don't have to.
Chris Kirkpatrick - his name is familiar because of that Eminem like "Chris Kirkpatrick, you can get your ass kicked". He was in some band with Justin Trousersnake.
He looks like he's still into the teenyboppers even though he's 50.
Cynthia Bailey - A washed up 55 year old model, apparent token, on one of those "real housewife" shows, which means she's rich, and has never done a days work in her life. Is probably doing it just because she "wants to".
Chris Kattan - Holy shit, its thats guy... Things obviously haven't worked out since that magical night at the Roxbury. He seems pretty well coked addled and degenerate. Probably won't do shit on TV apart from leave halfway through to go see his pharmacist. This could be a detox.
Mirai Nagsu - is the only one in red out of those skaters. Tonya Harding would have been way better. She did some mean shot back in the day. This is Mirai.
Teddi Mellencunt - Another entitled housewife from bloomingdale or some shit. I hate her already, and I hate that I googled her name. Hope Miesha switches and beats her up.
Shannon Moalker - Is apparently a 90s pageant model and former Miss World. She has many nudes on Google. Wood.
Todd Bridges - Wow... Willis is still alive. I only knew Gary Coleman by name from the show. He was better.
