Emmy Rossum says she and Adam Duritz, frontman of the rock group Counting Crows, broke up two months ago.
The 24-year-old actress is best known for her role in the 2004 movie, "The Phantom of the Opera," in which she played the female lead Christine.
Rossum is good at keeping her private life private, having been secretly married to music producer Justin Siegel for 18 months. She is believed to have started dating Duritz in September 2009, about a month after Siegel filed for divorce.
Rossum told USA Today recently that she is single after splitting from Duritz, who is 22 years her senior, but added that the two are "still very close friends."
The actress told the syndicated radio show "Valentine in the Morning" in mid-November that she met Duritz after The Counting Crows dared her on Twitter to sing with them.
"I was on tour with the band this summer. They invited me actually on Twitter," People magazine quoted Rossum as saying. "They dared me to come sing with them a song that I'd never sung before ... So I ended up on tour with the band, and it was very, very fun."
Counting Crows is known for hits such as "Mr. Jones" and "A Long December". In the 1990s, Duritz was linked to Hollywood heavyweights such as Mary Louise Parker, Courteney Cox and Jennifer Aniston. "I get why chicks dig him," Rossum told the Access Hollywood television show last year. "He's extremely kind, incredibly intelligent, thoughtful, creative and respectful."
Rossum will return to acting with the upcoming Showtime series, "Shameless," in which she plays the oldest daughter of a narcissistic alcoholic single dad, portrayed by William H. Macy. "Shameless" will premiere on January 9 on Showtime.
