Photo Coverage: What Happens at the HONEYMOON IN VEGAS Opening Night Party...

Honeymoon in Vegas, the new musical comedy with book by Andrew Bergman and score by Jason Robert Brown, opened last night, January 15, at Broadway's Nederlander Theatre (208 West 41st Street). After the curtain came down on the star-studded affair, cast and crew headed over to the Times Square Hard Rock Cafe to party down and celebrate the night. What happens in Vegas stays in Vegas, but what happened at the party -- we've captured below!

The cast of Honeymoon in Vegas includes Tony Award nominee Rob McClure, Brynn O'Malley, Emmy and Golden Globe nominee Tony Danza, David Josefsberg, Nancy Opel, Matthew Saldivar, Matt Allen, Tracee Beazer, Grady McLeod Bowman, Barry Busby, Leslie Donna Flesner, Gaelen Gilliland, Albert Guerzon, Sean Allan Krill, Raymond J. Lee, George Merrick, Jessica Naimy, Zachary Prince, Catherine Ricafort, Jonalyn Saxer, Brendon Stimson, Erica Sweany, Cary Tedder, and Katie Webber.

Honeymoon in Vegas tells the story of Jack Singer (McClure), a regular guy with an extreme fear of marriage, who finally gets up the nerve to ask his girlfriend Betsy (O'Malley) to marry him. But when they head to Las Vegas to get hitched, smooth talking gambler Tommy Korman (Danza), looking for a second chance at love, falls head over heels for Betsy. What happens next is anybody's bet!
