Tanning firm Fake Bake dropped the model yesterday when the News of the World revealed that she had been filmed snorting cocaine and offering their reporter sex for £10,000.
Anderton was secretly shot stripping to just a G-string and stilettos, asking the reporter if he wanted any cocaine after snorting some herself and arranging for two grams to be delivered to her by her dealer.
The former I'm A Celebrity... star reportedly admitted that she had to start selling sex so that she could pay for a new house.
Anderton said: "I'm great at sex. I'll look great on your f***ing arm. I'm a supermodel." She also hinted that she would take part in a threesome with another girl if she were paid enough for it.
A spokesperson for Fake Bake, for which Anderton had worked since 2005, said: "We operate a no-tolerance policy towards drug use so feel we have been left with no alternative than to terminate Sophie's contract."
