As a celebrity, the release of a sex tape is essentially a roll of the dice. You can either win big or lose your house on the gamble. A popular sex tape can turn B and C listers into A listers just like Pamela Anderson and Tommy Lee. A great sex tape can also turn a little bit of fame into a lot of fame (see Paris Hilton and Kim Kardashian).

Today Scarlett Johansson was announced as the new face of Mango Clothing Stores in Madrid. What do you think of her dark reddish hair? Do you prefer her as a blonde? She's also looking a bit thinner and less voluptuous these days. See more photos after the jump...
