Scarlett Johansson

Even though Scarlett Johansson's career as a singer is a hobby compared to her gig on the big screen, her approach to vocal performance is a far sight more ambitious than the average Hollywood starlet's. Johansson made her first venture as a singer in 2006, contributing a track to a non-profit compilation of songs recorded by actors. (She managed to fit this into the same year she became a spokesperson for L'Oreal and showed up on the cover of Vanity Fair in the buff!) And her auspicious 2008 debut, Anywhere I Lay My Head, flaunted some discerning taste: it was produced by Dave Sitek of TV on the Radio, and featured David Bowie, members of the Yeah Yeah Yeahs and 10 Tom Waits covers.
