Some may call it being unlucky in love, but for Minnie Driver, a failed relationship makes for good songwriting material. And that's exactly the case for her second album, Seastories.
"Much of this album is about someone who I loved very much and still have a great, wonderful friendship with even though it didn't work out," Driver, 37, told PEOPLE after her performance at J&R Music and Computer World in New York City on Wednesday. "My music is always from my experiences."
The Emmy-nominated actress – who dated her Good Will Hunting costar Matt Damon in the late 1990s, then was engaged to actor Josh Brolin in 2001, and was recently linked to illusionist Criss Angel – didn't elaborate on which former beau served as the inspiration for Seastories, but did say the ballad-heavy album "is about recovering. It's about knowing you'll always love again."
Driver's debut album, Everything I've Got in My Pocket, was released in 2004. Seastories came out earlier this month.
The British-born star will tour through August in the U.S. before hitting the Sept. 16 Emmy Awards, where she will vie for lead actress in a drama category. Driver said the nomination for her character Dahlia Malloy on FX's The Riches "was a surprise."
And what will be her choice of red carpet attire? "I'll be wearing a potato sack as far as I know," she joked. "I have no idea what I'm going to wear or how I'm going to find a dress, because I'm busy on tour."
