The Irish actor, 32, proposed the day after Christmas, while the couple were on vacation in Guernsey, an island in the English Channel.
"I guess he liked it, coz he put a ring on it. #engaged," Porter, also 32, Tweeted Thursday.
"I'm so bored of all this happiness and sex. I'm getting married," O'Dowd quipped via Twitter the same day, later describing himself as a "very happy & lucky boy."
The fun-loving couple also Tweeted a picture of themselves as "Fred and Rose" in matching snowman-emblazoned sweaters on Christmas Day.
