Romantic Nick Grundy had a Valentines hit with his fiancee when he serenaded her with a rock choir.
Estate agent Nick, 29, secretly gathered 35 singers at the office where web designer Jennifer Coker works.
He arranged for colleagues to coax her out while the Cambridge Rock Choir hurriedly took their places.
Stunned Jennifer, 28, was then wooed with a rendition of the Take That and Bee Gees hit “How Deep is Your Love”.
Jennifer, a Take That fan, said: “It was a bit of a shock to say the least.
“I can’t say it would be my first choice of Valentine’s Day treats, as lovely as it was, because I hate surprises.
“But he really has excelled himself and I’m very proud of him.”
The couple who live in Royston, Herts., got engaged in New York City when Nick got down on one knee on the Brooklyn Bridge.
He said: “I wanted to show her how much I love her. The idea was to make her go red and laugh.
“She says she doesn’t like surprises but deep down I think she does.”
