One posted: "Less than a day in the #CBB house they show India’s chest? Is that because she is trans they're allowed to? Couldn’t see them showing off Ann Widdecombe’s chest on national television, any privacy?"
A second added: "Oh come on, did they really need to show India’s exposed breasts?? Like, let them have a little privacy on air ffs CBB, I hope she’s ok with that whenever she leaves the house?"
A third chipped in: "Year of the woman! *close ups of the women's arses when they're working out and a gratuitous topless India*"
