Rosario Dawson certainly has good taste in men, yowza. We totally approve of her hottie boyfriend Mathieu Schreyer (aka DJ Mr. French). The happy couple strolled around Soho yesterday in New York City, New York. Mathieu Schreyer is a host on KCRW radio and resident DJ at Hyde and Bar Marmont in Los Angeles, California. And of course, Rosario has a very successful career as both a singer and big time actress.
