The image of Ryan Gosling and Rachel McAdams going at it in the rain in "The Notebook" will forever be etched in many women's minds. And if Gosling had it his way, his songs with Dead Man's Bones would be just as indelible. We're not sure about that, but the folk-rock duo's 2009 debut album, which featured a children's choir throughout, was memorable.
Juliette Lewis' look and attitude scream "rock star" more than Oscar-nominated actress, so it's fitting that Lewis' current focus is on her music career. The "Cape Fear" and "What's Eating Gilbert Grape" actress tears up the stage with rough-around-the-edges swagger when she performs with her new band the New Romantiques, previously rocking the same vibe with former act Juliette Lewis & the Licks.
Eddie Murphy's comedic legacy is undeniable, yet the "SNL" funnyman certainly didn't laugh over his biggest hit, 1985's "Party All the Time," as much as music fans did. The so-bad-it's-good track, produced by Rick James, features Murphy pondering why his lady friend is so promiscuous. But the "Beverly Hills Cop" actor didn't stop there: He released two more albums of pop and R&B following his hit.
Former Phantom Planet drummer Jason Schwartzman can't seem to make up his mind about whether he's a musician or an actor, though he's currently focusing on the former. His HBO comedy "Bored to Death" was cancelled after a three-year run in 2011, but he's currently involved in a TV-movie reboot. Hopefully, won't stop Schwartzman, who scored his first role at age 17 in Wes Anderson's "Rushmore," from putting out music from his solo project, Coconut Records, on the side.
Hilary Duff is surprisingly masterful at moving from one field to another. She rode the wave of her "Lizzie McGuire" success straight into a film and music career via the Disney Channel show's official movie and its soundtrack, which featured her hit debut single, "Why Not." Duff was on top of the teen world for a while, scoring three platinum albums in the mid-2000s, starring in the "Cheaper By the Dozen" films and launching her own clothing lines.
Kevin Costner possesses the tan and friendly face of a picture-perfect country singer, so slap a cowboy hat on the "Field of Dreams" actor and he's ready to take Nashville. His band, Kevin Costner and Modern West, kicked off with a bang in 2007, completing a worldwide tour including stops at major NASCAR races. The band's debut album, "Untold Truths," followed in 2008, making minor waves on the Billboard country charts.
Art imitated... art when Michael Cera joined Sub Pop group Mister Heavenly as its bassist in late 2010. The actor, who got his start as George Michael Bluth on "Arrested Development," played the role of nerdy-hipster bassist in films including "Nick & Norah's Infinite Playlist" and "Scott Pilgrim Vs. The World."
Billy Bob Thornton
"Sling Blade" was his masterpiece; Angelina Jolie was his tabloid fodder; music became his side gig. "Armageddon" actor Billy Bob Thornton's career as a singer-songwriter spans three country albums, and a stint fronting blues-rock cover band, Tres Hombres, before moving on to the rockabilly stilings of The Boxmasters in 2007.
Jenny Lewis once told Billboard that she's had "a very bizarre American life," and the child actress-turned-indie rock icon hit the nail on the head. Standouts in her film career include teen films "Troop Beverly Hills" and "The Wizard," as well as a minor role in "Pleasantville." Soon after, she transitioned into Los Angeles' rock world, bonding with fellow Rilo Kiley bandmate Blake Sennett, a fellow child actor who appeared on "Boy Meets World" and "Salute Your Shorts." With Rilo Kiley now officially broken up, she'll spend much of 2013 on the Postal Service's reunion tour.
Any musical talent Johnny Depp possesses will always be overshadowed by his international sex symbol status and emoting chops, but that doesn't stop the actor from trying. He played guitar in the short-lived '90s project P, which included Butthole Surfers frontman Gibby Haynes and Flea of the Red Hot Chili Peppers, and has recorded solo work on his guitar and performed alongside big rock names like Iggy Pop and Pearl Jam's Eddie Vedder. It somehow makes him even more irresistible to women.
