The supermodel went undercover in a pizza parlour to see if customers recognized her.
In the CBS show, I Get That A Lot, she insisted she wasn't the German-born catwalk beauty.
And if anyone suspected she was lying, she would tell them: 'I get that a lot.'
One customer suggested she should turn to pole dancing to make some extra cash.
She then slapped her backside and showed off her stomach.
Eventually, the 37 year-old revealed the truth.
Also on the show were rapper Ice-T, who tried to pass himself off as a shoe salesman, and Paris Hilton, who attempted to go incognito at a petrol station.
