Hours before the nuptials were set to start on Saturday, Sports Illustrated Swimsuit model Brooks Nader was spotted approaching the resort with her new boyfriend, Prince Constantine Alexios of Greece and Denmark.

The couple weren’t yet in their wedding clothes. Nader, 27, wore a black minidress beneath a black leather jacket, while the 25-year-old prince sported a loose-fitting shirt and jeans.

On the eve of the wedding, employees could be seen assembling expansive wooden flooring out front beneath a white tent with five turrets, surrounded by a plume of purple hydrangeas.

Beyond the tent, guests played croquet on the lawns framed by a sliver of ocean as valets and delivery vans arrived with more materials.

Outside the chapel where Culpo and McCaffery are set to tie the knot, dozens of employees wearing all-black were hard at work erecting an elaborate floral arch Saturday morning.

The workers spent several hours assembling the 12-foot leafy entranceway peppered with grassy fronds and large white hydrangea blooms.

By 2 pm Saturday the rehearsals were in full swing - with chapel staff practicing a synchronized movement across the street with a flotilla of umbrellas which they'll use to shield the bride from public view during her grand entrance later

Meanwhile, dance music began blasting from the canopy erected out front of the hotel, the inside of which has now been blocked from street view with white drape

A winding path through the manicured hotel gardens takes guests down to a private beach overlooking the azure Block Island Sound.

McCaffery and Culpo have been enjoying the beach - but they were nowhere to be seen on Friday.

They set off on their 3,000-mile journey from Van Nuys, Los Angeles, on a private plane decked out with rose petals and flowers on Monday.

They even brought their dog Oliver with them to the New England state where Culpo grew up and won her first major beauty pageant - Miss Rhode Island 2012.

They were greeted by a huge 'Mr & Mrs' sign sitting outside the aircraft before they made their way on board.

Culpo and McCaffrey were treated to champagne and a three-course meal on their wedding flight, along with a digital photo frame consisting of some of their cutest photos together.

Culpo recently said she wants Oliver to be heavily involved in the wedding ceremony this summer, setting her sights on their goldendoodle being a ringbearer on the day.

McCaffrey is currently enjoying the NFL offseason after the 49ers' gut-wrenching defeat to the Kansas City Chiefs in last season's Super Bowl.

The running back had a remarkable 2024 campaign on an individual level, ranking first in the NFL for rushing yards (1,459) and fourth for touchdowns (14).
