Congratulations are in order for Copacabana singer Barry Manilow who reportedly married his manager and long-time partner Garry Kief in a secret wedding last year.

The 71-year-old is said to have told the "20 to 30 guests" invited to the private ceremony that they were attending a "lunch" at his home in Palm Springs, California, in April 2014. A source told People magazine of the top secret nuptials: "It was a surprise."

The publication claims that the legendary singer and Kief, 66, did not sign any paperwork to make their marriage official, but both are said to be wearing wedding bands.

"[They] are committed to one another and have been for a very long time. They have a great relationship. Garry has always been there for Barry," the insider told the magazine.

The Could It Be Magic hit-maker has never addressed his sexuality publicly but the source claims he now "doesn't care what people think".

"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. He's in love and happy," they said.

Another friend of the couple described the ceremony as "beautiful" to the National Enquirer, revealing: "Barry has lived a very secretive life and the wedding was no different! Barry and Garry did not tell friends or family that the occasion was their wedding. It was a beautiful wedding and consummated their lifelong love affair."

During a TV appearance in the UK last year, Manilow was seen wearing a wedding band on his ring finger but the National Enquirer has been the first to break the news this year.

If reports are true, it is not the US singer's first trip up the aisle as he is believed to have married Susan Deixler in 1964, but their union only lasted one year.
