Girls' Generation's Tiffany unintentionally promoted the Italian car 'Fiat 500'.

On a recent episode of 'Strong Heart', she confessed, "I bought a new pink car." When the MC's guessed that it was like Paris Hilton's pink Bentley, she hurriedly said, "It's not that expensive. You have to remove a few 0's since it's a compact car."

After the show aired, her fans went investigating and found out that given the price range, pink color, and it being a compact car, it matched with the profile of the 'Fiat 500'. Fiat offered a special pink Barbie line for the car. Because of Tiffany supposedly owning the car, the term 'Fiat 500' shot up to #1 in the real-time search rankings.

However, SM Entertainment denied the rumors and said, "Tiffany's car isn't an expensive car. She bought the pink Spark from Chevrolet."
