The glamour model and Page 3 idol couldn't help but expose herself as she attempted to cover herself up after stepping out of the shower.
Protesting that she had forgotten her towel, Banghard then streaked through the lounge.
She is the second housemate to expose themselves to the Celebrity Big Brother cameras after Rylan Clark dropped his onesie before a horrified Neil Ruddock in the garden last week.
Banghard and Heidi and Spencer Pratt had been nominated by their fellow housemates yesterday (January 13).
They join Rylan and Claire Richards, who were chosen by Speidi following their return from the luxury basement on Friday (January 11), in facing the public vote.
Banghard has been named as the favourite to be evicted on Wednesday (January 16), with one bookmaker commenting that she is "too nice" for the house.
