Actress Scarlett Johansson has become the lucky winner of a luxury home in Florida.

The Lost In Translation star had the winning key that unlocked the door of the swanky South Beach condo, which she won in a special Superbowl promotion against other stars including Robert Downey Jr and Kevin Federline.

The prize is a year-long lease on the home worth $2.2m.

The condo, which is said to have been completely renovated, has three bedrooms, three bathrooms and brand new fixtures and fittings. Johansson has yet to reveal when she intends to move in.
