Barry Manilow has married his longtime manager Garry Kief, according to multiple reports. Manilow has not commented on the reports.

The pair wed in a private ceremony in front of 20-30 guests at Manilow's Palm Springs, California home.

"It was a surprise," a friend said of the nuptials. The guests were reportedly told they were attending a "lunch" -- and soon realized that it was a wedding.

Manilow's longtime friend Suzanne Somers was the best man at the ceremony and Marc Hulett, Barry's assistant since the 1980s, oversaw the proceedings after he registered online to become a minister.

A source close to the entertainer who said that Barry and Garry "are committed to one another and have been for a very long time."

The source adds, "They have a great relationship. Garry has always been there for Barry."
