According to this CNN interview (and probably old news, but I haven't been as au courant with the celeb news as I'd like), Scarlett Johansson has an album of Tom Waits covers coming out:
Q: What about this album you're releasing? It's all Tom Waits covers?I can imagine her singing "Downtown Train", which is the one I can most imagine with a female voice, since I've heard the Patty Smyth and Everything But the Girl versions, but on the other hand, would she take on, say, "Bottom of the World"? Much as I respect Johansson's taste for Tom Waits, I'm not sure about this...
JOHANSSON: I've always been a huge fan of Tom Waits and I had this kind of golden opportunity to make an album however I wanted and it's kind of a dream chance. ... Originally I thought that I would do an album of standards and I wanted to include a Tom Waits song. And I don't know, I thought maybe everybody does standards, and so, I see Tom Waits as being kind of a composer of modern standards and so it seemed appropriate that I could interpret his songs. Obviously, it's not an album where I'm trying to sound like him. It would be impossible. He writes such beautiful songs and incredible melodies and they're so cinematic and kind of open-ended so I felt like it would be something that I could be inspired by.
