Rosen was born in Tel Aviv, Israel and moved to Boston, Massachusetts at the age of three. She began modeling when she was 18 years-old while possibly attending Amherst College. After experiencing cult status as a model for Score magazine and appearing on The Jenny Jones Show, Rosen entered the porn industry at the age of 20, and has worked for almost every hardcore production company in "Porn Valley", California as well as many in Miami, Florida and throughout North America. She first appeared on screen as the box covergirl of Hustler's Busty Beauties #7 and shortly after that, appeared on the cover of Big Butt magazine. It is projects like these that has made Rosen known for both her ample breasts and buttocks and a favorite among "urban" porn fans. She also discovered Score model Eve Tyler. She is well known for her intensity in lesbian and anal themed performances. Daphne has recently displayed her talent for female ejaculation, often during lesbian performances. Rosen has performed in over 150 pornographic movies in a little over two years.
