Apparently the chat is now suggesting the Reggie (Regina) Bird that joined the conversation last night (as pictured in your post) is nothing more than a sock puppet account portraying her, although this has not yet been officially confirmed. Just random claims from users in the chat.
The account, named BBREGGIE03, was even made a moderator by bigbrotherau for the Live Chat. Pending some form of confirmation update on Reggie’s socials…
And if the chat’s claims are true, then we may have been talking to a sock puppet account.
