How is Megan eligible for CBB, but Winston BB15 wasn't?
 

I don't really know who she is, and Google isn't much help, but is Ex on the Beach all she's done? Winston from BB15 had been in three reality shows (I've not seen any of them, so I don't know how much) but he was in the civvie?

Ex on the Beach is more a high profile reality show and Megan was in a more high profile role on it than anything that Winston was in, although I agree that the lines between civilian and celebrity are ridiculously blurred nowadays

Winston probably didn't mind a menial fee.

The producers probably are just going for who's available tbh - it's on twice a year so they're running out of people to put in.

they play rock, paper, scissors to decide who goes in what series

Not Winston

I guess people from 'girlfriends' or whatever that show is will be on CBB soon because of them having 2 CBBs a year...they must be running out of celebs
