O'Donnell will cut the ribbon prior to the three-hour "Fan Festival," which is being held at the Madame Tussauds on West 42nd Street. The ribbon cutting is scheduled for 2:45 PM and will be followed by brief remarks by O'Donnell and a performance by Rosie's Broadway Kids.

The 3-6 PM Madame Tussauds event — featuring special activities hosted by cast and crews of participating shows — allows "children and their families . . . to tour the attraction for free and enjoy a number of unique theatre activities, including special theatrical makeup stations, Broadway dance lessons, karaoke and more. A number of Broadway stars will also be on hand to sign autographs."

Among the shows participating in this year's Fan Festival are Altar Boyz, Avenue Q, Chicago, A Chorus Line, The Color Purple, Come Back Little Sheba, Curtains, The Fantasticks, The Farnsworth Invention, Grease, Hairspray, Is He Dead?, Legally Blonde The Musical, The Lion King, Disney's The Little Mermaid, Mamma Mia!, Mary Poppins, Monty Python's Spamalot, The Phantom of the Opera, Rent, Spring Awakening, Stomp, Wicked, Xanadu and Young Frankenstein.

Kids' Night on Broadway (KNOB) — the annual event during which young people ages 6-18 can attend a Broadway show for free when accompanied by a full-paying adult — is being held in Manhattan Feb. 5, 6, 12 and 13, and nationwide throughout the winter and spring.

In a previous statement O'Donnell said, "I am thrilled to be associated with this wonderful program, which helps to expose young people to the wonderful world of Broadway theatre. Since its inception, over 200,000 people have participated in Kids' Night in New York alone, and we look forward to reaching even more families with the message that there is no greater entertainment than Broadway."
