Emmy Rossum, raised by a single mother, has opened up about her feelings about the father she barely knows.
"They separated when my mom was pregnant," the actress told USA Today
. "I've met him twice. I've been this glossy, red-carpet version of me and not talked about myself for a long time."
Rossum, who just turned 21, has been lying low lately, but she hasn't been taking a break. She turned to music, a talent she developed singing with the Metropolitan Opera as a child, and is releasing her debut album, Inside Out
"The last track on the album ("Anymore") is about how being abandoned shouldn't make you feel ashamed ... I miss him, or I miss the idea of what he could be," she said. "But a lot of people have filled that void."
In particular, she says, her fellow actors have helped her cope with her non-traditional family life.
"I've signed on for three [new films]. I grew up with a single mom and no siblings. When I'm on a film, I have so many surrogate siblings. I'll never give up on that," said the actress who has starred in The Phantom of the Opera
, Mystic River
and The Day After Tomorrow
As for reaching the legal drinking age, she finds a joy in shocking people.
"I love a whiskey sour, and I know most people can't believe a small-framed girl like me can drink a whiskey sour, but I can," she says, adding: "And I like Bellinis."
