Rosario Dawson is single again after splitting from French DJ Mathieu Schreyer, according to a report.
 
The "Sin City" star began dating Schreyer in 2008 and were last seen out together in public at a Prince concert in Los Angeles on April 23.
 
But UsMagazine.com claims the couple has since parted ways due to their busy schedules.
 
A source says, "They were always in separate places because of their careers."
