​Barry Manilow reportedly marries longtime manager Garry Kief

Barry Manilow has married his longtime manager Garry Kief, according to multiple reports.

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

"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, 71, has not commented on the reports, which first showed up in the National Enquirer.

We may not get confirmation from Manilow himself -- the singer of such hits as "I Write the Songs" has been largely quiet about his personal life.

In 2012, he told the U.K.'s Telegraph, "I am a private guy. You can only come into my world if I invite you in. From the very beginning that was the rule."

Manilow was briefly married to Susan Deixler in the 1960s.
