The Wanted's Siva Kaneswaran is engaged to his girlfriend of six years, Nareesha McCaffrey - but she initially said no.

When McCaffrey threw a surprise birthday party for the singer, the 25-year-old Dubliner turned the tables with his proposal.

In an interview with Hello! magazine, he said: "It was like a military operation to plan the proposal. I couldn't even tell the other boys in the band in case they blew the surprise."

Kaneswaran proposed on bended knee with a specially designed, three-carat diamond solitaire ring.

"I said to her I wanted a present I would always remember this year by – 'for you to be my wife'," he recounted.

"I'd bought the ring months before; I'd been trying to figure out the right time."

Explaining her initial rejection, shoe designer McCaffrey said: "I'm still in shock. I don't like surprises and he really surprised me, but I was so happy. I can't wait to start planning the wedding."
