The wedding was held at Barry's Palm Springs, Calif., home and was attended by 20-30 guests. The guests, according to a source, were told they'd simply be attending a "lunch" at the home, not nuptials.

"It was a surprise," a source said.

Not only was the wedding a surprise, but many of the singer's fans were surprised to hear that Barry was gay.

"He's at a point now where he's got his career and personal life in a great place and he really doesn't care what people think," a separate source tells PEOPLE, adding that he never hid is sexual orientation. "He's in love and happy."

According to the National Enquirer, who was first to report that news, Barry and Garry have been together for more than 30 years.
