Ivana Trump peeled off her clothes to reveal her underwear on Celebrity Big Brother yesterday.

The socialite joined Page 3 model Nicola T to act as a model during a life drawing task.

Dane Bowers' drawing was deemed the best, earning him - and the models - a special prize.

The scenes, which were shown on Big Brother's Little Brother, will air on Channel 4 tonight.
