Lacey Banghard stripped naked in the 'Celebrity Big Brother' house.

The 20-year-old glamour model shocked viewers by racing across the outdoor patio in the nude on Monday morning (14.01.13) in full view of the cameras, while barely concealing her modesty with her hands.

Speculation is rife her naked antics could be a last ditch attempt to canvas support after being put up for eviction alongside Steps singer Claire Richards, 'X Factor' contestant Rylan Clark and 'The Hills' reality stars Spencer Pratt and Heidi Montag.

The nominees will face the public vote on Wednesday night (16.01.13), with Lacey receiving six nods from her fellow housemates, while resident troublemakers 'Speidi' were put forward by every single constant on the Channel 5 show.

The busty babe later raised a few eyebrows as she suggestively snacked on a banana, prompting her co-stars to brand her exhibitionist behaviour fake.

Speaking in the Diary Room, jockey Frankie Dettori said: ''She's making an extra effort to sing and dance and stand out, when I don't think it's really her.''

Meanwhile, former footballer Neil 'Razor' Ruddock is irritated by Lacey's bad habits and thinks her unladylike behaviour is to blame for her dwindling popularity in the house.

He ranted: ''I've got two pet hates when it comes to women. She burps all the time and thinks it's funny and her language is terrible for a young woman. It really winds me up.''
