Earlier this month (SEP05), reports said the couple were planning a low-key New Year's Eve (31DEC05) ceremony, and while they won't confirm the date, they admit they're planning to become husband and wife.
O'Connell, 31, proposed to Romijn, 32, over the weekend (1618SEP05) in the New York City apartment he grew up in.
They say in a joint statement, "We couldn't be happier and are looking forward to the next chapter of our lives."
Romijn's divorce from actor John Stamos was granted in March (05), almost a full year after their split was announced. She began dating O'Connell last year (04).
