LOS ANGELES - Steve Martin married girlfriend Anne Stringfield during a ceremony at his Los Angeles home, his publicist said.

Former Nebraska Sen. Bob Kerrey, a friend of Martin's, presided over Saturday's ceremony, Alan Nierob said. Saturday Night Live creator Lorne Michaels was Martin's best man, he said.

Most of the roughly 75 guests — who included Tom Hanks, Diane Keaton, Eugene Levy, Carl Reiner and Ricky Jay — were not told that he and Stringfield would wed when they were invited to his home for a "party," Nierob said. The ensuing nuptials were a surprise to them, he said.

Martin, 61, was previously married to actress Victoria Tennant, whom he divorced in 1994 after about 8 years together, Nierob said.

It was the first marriage for Stringfield, 35, a writer and former staffer for The New Yorker magazine.

The two had dated for about three years, Nierob said.

Martin delivered his vows sporting an Inspector Clouseau mustache he let grow in for his appearance in the upcoming sequel to 2006's "Pink Panther" remake.

His other movies include "Planes, Trains & Automobiles," "L.A. Story," "Parenthood," and "Father of the Bride."

His novel "Shopgirl" was made into a 2005 film starring himself and Claire Danes.

The wedding was first reported by The Insider, a CBS celebrity news show.
