A source tells PEOPLE that LuAnn de Lesseps will likely be getting engaged to boyfriend Thomas D'Agostino Jr. soon.
The pair spent a romantic holiday getaway together, ringing in the new year in Palm Beach, Florida.
They were spotted at several parties and at the Brazilian Court Hotel, according to the source. Most notably, the reality star and her new beau were seen shopping for an engagement ring at the city's Graff Diamonds.
While the romance blossomed quickly, the couple has been spotted out several times in both New York City and Sag Harbor, New York.
Friends say that de Lesseps is completely "over the moon and so happy," according to the source, and a big "announcement" is imminent.
De Lesseps shared a photo with D'Agostino on Twitter over the weekend, writing, "First time playing golf with Tom! #PalmBeach #Breakers #love."

Interestingly, the businessman was briefly linked to de Lessep's co-star Ramona Singer last fall. It doesn't sound like the "Girl Code" was broken, however; the source says that D'Agostino only had eyes for de Lesseps.
De Lesseps, 50, was married to Count Alexandre DeLesseps, 66, from 1993 to 2009. The pair share two children, son Noel and daughter Victoria.
