The 41-year-old actor — who has appeared on Broadway in Assassins, Urinetown, Jane Eyre, Carousel, Cyrano - The Musical and Beauty and the Beast — had been indicted in 2006 on nine counts of engaging in criminal sexual acts, sexual abuse and endangering the welfare of a child.
Barbour, AP reports, admitted that he sexually touched a 15-year-old female fan when she visited him backstage following a performance of Jane Eyre in 2001 and when she later visited his apartment on New York's Upper West Side.
Barbour will not have to register as a sex offender because he pleaded guilty to a misdemeanor. The lesser charge, however, was in exchange for a 60-day jail sentence and three years of probation. Sentencing will take place Feb. 29 at Manhattan's State Supreme Court.
Barbour received a Drama League Award for his lead role as Edward Fairfax Rochester in Jane Eyre. He has appeared in such films as "Eight Crazy Nights" and has guest-starred on such television shows as "Sex and the City" and "Ed."
On Dec. 6, 2007, Barbour pleaded not guilty to charges of sexually abusing the 15-year-old fan. The woman, who was 20 last year, came forward before the five-year statute of limitations expired.
