"I'm so bored of all this happiness and sex. I'm getting married," he wrote. Added his 32-year-old fiancee, via Twitter : "I guess he liked it, coz he put a ring on it. #engaged."

That ring, Porter tells the local Guernsey Press, is not the traditional engagement diamond, but an emerald.

"The ring is gorgeous -- an emerald, as he is Irish, and green to replace a green ring of my mum's that I have worn on that hand since I was 16," the bride-to-be told the paper.

According to Porter, the couple is considering a summer 2012 wedding.
