Scarlett Johansson (born November 22, 1984) is an American actress. She rose to fame with her role in 1998's The Horse Whisperer and subsequently gained critical acclaim for her roles in Ghost World, Lost in Translation (for which she won a BAFTA), and Girl with a Pearl Earring, the latter two earning her Golden Globe Award nominations in 2003.

Johansson is a Democrat. In 2004, she campaigned for John Kerry in the 2004 presidential election. She was quoted as saying, of George W. Bush's re-election, that "[she was] disappointed. I think it was a disappointment for a large percentage of the population." Johansson campaigned for Barack Obama in Iowa on January 2, 2008; her efforts were targeted at small groups of younger voters, including Cornell College students. She has also taken part in the anti-poverty campaign ONE which was organized by U2 lead singer Bono.

Johansson says she has a connection to older men, and could not see herself dating anyone under the age of 30. She does not discuss her personal life with the press, saying "it's nice to have everybody not know your business." This has not stopped Johansson from sharing "select" opinions and personal details. Johansson's ex-boyfriend (and member of the band Steel Train), Jack Antonoff, wrote lyrics that refer to Johansson in the song "Better Love." Antonoff alludes to Johansson in the song "2 O'clock." She has been linked to many famous men, including Derek Jeter, Benicio del Toro, Jared Leto, Justin Timberlake and her Black Dahlia co-star Josh Hartnett. They dated for about two years until the end of 2006, with Hartnett citing their busy lives as the reason for the split. She is currently dating Canadian actor Ryan Reynolds, but has denied arising rumors of their engagement.

Johansson says she does not believe in monogamy, and opined it is not human nature to be with just one person. She also said "contrary to popular belief... [she is] not promiscuous" and she works "really hard" when she is in a relationship "to make it work in a monogamous way." She gets tested for HIV twice a year, and has said "it's part of being a decent human" and it is "disgusting" and "irresponsible" when people do not do so.

Johansson is a cheese fanatic, saying: "My greatest vice is cheese. Nothing else reigns over my life." She has criticized the media and Hollywood for promoting an image that causes unhealthy diets and eating disorders among women, saying "that being ultra-thin is not sexy at all. Women shouldn't be forced to conform to unrealistic and unhealthy body images that the media promote."

Johansson appeared on the cover of the March 2006 issue of Vanity Fair in the nude with Oscar-nominated actress Keira Knightley and world-renowned fashion designer Tom Ford.

In March 2006, she topped the U.S. edition of FHM's poll of the sexiest women alive (in the UK edition Johansson was third). In 2007, Maxim named Johansson #3 in their Hot 100 issue. In November 2006, Johansson was named "Sexiest Woman Alive" by Esquire. In February 2007, she was named the "Sexiest Celebrity" of the year by Playboy.

About her religious affiliation, Johansson says: "That's a very personal question. I would rather not answer." She celebrates a "little of both" referring to Christmas and Hanukkah. She dislikes when celebrities thank God or Jesus in their award acceptance speeches. She described herself as Jewish when she was talking about Woody Allen. "I just adore Woody," she says. "We have a lot in common. We're New Yorkers, Jewish. We have a very easygoing relationship".
