The Hairspray composer had two reasons to celebrate on Saturday (26Mar16) - his partner, Lieutenant Commander Louis Mirabal, was honoured during a retirement ceremony in New Jersey, honouring his 20 years of service in the military.

And following the event, Shaiman and Mirabal exchanged vows in a wedding ceremony officiated by Broadway producer Tom Kirdahy.

Actress Julia Murney was among the many stars who were on hand to witness their union, and she took to Instagram.com to share photos from their big day. In one shot, Nathan Lane stands at the podium, where he read a patriotic passage as Shaiman's score to 1995 film The American President played in the background, while actress Jenifer Lewis belted out the U.S. National Anthem.

Lewis' Beaches co-star Bette Midler was also on hand for the wedding, as well as Patti LuPone, Whoopi Goldberg, and Darlene Love, among others.
