As previously reported, O'Hara and her husband, actor and musician Greg Naughton, are expecting the birth of their first child. O'Hara, who earned her third Tony nomination for her performance as Ensign Nellie Forbush, will return to South Pacific on Oct. 6.

During O'Hara's absence, recent Grease star Laura Osnes will assume the role of Nellie Forbush. Osnes joins the Lincoln Center Theater production March 10. The March 8 performance of South Pacific will feature Garrett Long in the role of Nellie.

O'Hara was also honored with Tony nominations for her work in the Tony-winning revival of The Pajama Game and the Tony-winning musical The Light in the Piazza. On Broadway she has appeared in Jekyll & Hyde, Follies, Sweet Smell of Success and Dracula, the Musical. Her album, "Wonder in the World," is currently available on the Ghostlight Records label.

Tickets for the Lincoln Center Theater revival of South Pacific are available at the Vivian Beaumont box office (150 West 65th Street), at Telecharge.com or by visiting www.LCT.org.
