Winona Ryder's alleged supplier has been caught! Doc-to-the-stars Jules Lusman, who had his medical license revoked last week, has been accused of overmedicating celebs like Ryder and singer-actress-hellraiser Courtney Love. Ryder had 37 prescriptions filled by 20 doctors from January 1996 to December 1998, according to the actress's probation report. Lusman denies any wrongdoing.
