Last week she announced her engagement to actor Ryan Reynolds. And in less than two weeks, the 23-year-old will release her debut album.
Johansson and her music producer, TV on the Radio's David Andrew Sitek, call her sound "Tinkerbell on cough syrup."
Last summer the pair took a road trip from Los Angeles to Maurice, La., where they recorded her album, Anywhere I Lay My Head, – in which she mostly covers classic Tom Waits tunes – in five weeks.
"I'm not trying to prove anything on this album," Johansson says in a statement. "I just love (Tom Waits') music."
The album also features one new track called "Song for Jo," which Johansson wrote with Sitek. "I had never really written a song before. I'd only written poems or short stories," she says.
"It was a memory of someone that's very close to me: a vague and blissful memory of my wanton youth or whatever. It's a song about friendship, I think."
David Bowie sings backup on two tracks: the first single, "Falling Down," and "Fannin Street."
Is Johansson concerned about what her movie fans might think? "I never worry about that kind of thing," she says. "I hope people enjoy it."
Anywhere I Lay My Head will become available May 20 on Rhino Records.
