Billy Joel gets married

Billy Joel and Alexis Roderick got married Saturday, surprising guests at their annual Fourth of July party.

People magazine first reported the wedding.

Joel, 66, and Roderick, 33, are expecting a baby this summer.

Joel's daughter Alexa Ray Joel, 29, (also daughter of Christie Brinkley) was in attendance, and New York Gov. Andrew Cuomo presided over the event, People reports. This is Joel's fourth marriage.

Do you think their first dance was to "Just the Way You Are" or "She's Got a Way"?
