Kellie Pickler and Kyle Jacobs are married! The singer, 24, and songwriter Jacobs, 37, eloped on Jan. 1, exchanging vows in the Caribbean. Her rep tells PEOPLE that it was a “small, intimate ceremony.”

The couple, who have been together since 2008, were engaged on June 15 on a Florida beach at sunset. June 15 also represents the birthday of Pickler’s late grandmother Faye. But despite the sadness, the day “turned out to be the most amazing day of my life,” Pickler admits. “My whole world changed. We both feel like we got my grandmother’s blessing.”

Pickler recently posted an adorable black and white Twitter picture of the lovebirds with the caption “crazy about this man.”

It seems that New Year’s Day, or rather 1/1/11, is a favored wedding date, as Shania Twain and Frederic Thiebaud also tied the knot that same day in Puerto Rico.

Pickler, who made her big break on ‘American Idol’ in 2006, has since released five Top 20 charting singles, including her Top 10 hit’Best Days of Your Life’ with BFF Taylor Swift. Her latest single, ‘Makin’ Me Fall in Love Again,’ reached No. 30 on the Hot Country Songs chart.

Congrats to Kellie Pickler and Kyle Jacobs!
