I'm going out on a limb way early and tipping Ray J for the win.
Only know him from the Kim K sex tape, could not name one song of his but he seemed from his intro he might be funny, doesn't take himself to seriously.
I just can't friggin stand that James, he was an absolute arsehole in his series and loves himself to death. I'm a bit over "i'm a really nice guy Callum Best", he was good in his series but I watched him on famously single and he is an angry drunk a bit of a turd and quite fake overall.
Spencer and Heidi - professional reality show performers, seen it all before. Blah.
As usual all the rest are unknown to me.
Bring it on can't wait for it to get feisty.
