Brooks Nader officially has moved on amid her divorce from her estranged husband, Billy Haire.

The Sports Illustrated model hard launched her relationship with Prince Constantine Alexios of Greece and Denmark at Olivia Culpo and Christian McCaffrey’s wedding in Rhode Island over the weekend.

Photos from the nuptials show the royal with his arm wrapped around Nader’s waist as they stand by their table to watch the newlyweds dance.

Nader, 27, looked stunning in a strapless navy blue sequined gown, accessorizing simply with a Cartier love bracelet. The model, who briefly dyed her hair platinum following her divorce announcement, returned to her brunette locks.

Her royal plus-one, 25, looked dapper in a classic tuxedo for the nuptials.

It’s unclear when the two began dating, though they sparked romance rumors last week when they were spotted on a stroll together in New York City.

Page Six broke the news in early May that Nader and Haire were divorcing after four years of marriage.

Our sources said the former couple had been living apart for months but have been amicable as they navigate their split.

By the end of the month, we reported that the cover model was “loving single life” and spending plenty of time in the Hamptons.

Nader was spotted over Memorial Day Weekend at the famed Surf Lodge in Montauk watching a surprise performance by 50 Cent, along with a VIP crowd that included newlyweds Millie Bobby Brown and Jake Bongiovi, and actor Liev Schreiber.

We heard Nader stayed at the Montauk home of PR exec and Kourtney Kardashian’s BFF Simon Huck.

She was “hanging with the gays,” during her weekend out East, the source shared.
