The royal couple is currently on vacation in Mustique, and, according to Hello!, they spent a wild evening out partying with rock royalty. They reportedly attended an event at the island's famed Basil's Bar, and rubbed elbows with Mick Jagger's daughter Jade at a "Splash of Gold"–themed event.
The Duke and Duchess of Cambridge hit the party "on the early side," according to the report, and both looked "island chic" for their big night out, with William rocking a T-shirt by island brand Pink House Mustique. "They were there for the cocktails segment and kept it rather classy," a source told Hello!
The couple is vacationing in Mustique, seemingly one of their favorite destinations, with Kate's parents, Carole and Michael Middleton. (Their kids are also on the island, but stayed home on the night their parents hit the town.) This is at least the fifth time that Will and Kate have vacationed on the small island in the Grenadines. They first touched down in Mustique in 2008, then returned in 2013 for a babymoon, shortly before Prince George was born. Then they headed back six months later with their new baby on board. The family also celebrated Carole Middleton's 60th birthday on the island, in 2015, and reportedly stayed in a $25,000-a-week villa with a staff of six and a 64-foot pool. During their previous trips, Hello! notes that they took full advantage of everything the island has to offer, including tennis, snorkeling, scuba diving, and cocktails at the five-star Cotton House resort.
The Middletons and the Jaggers aren't the only famous families with a penchant for island living. Earlier this year, Ally Hilfiger, daughter of designer Tommy Hilfiger, hosted a "Rock 'n' Roll"–style wedding at the glam destination.
This is the first big vacation that Prince William and Kate Middleton have taken now that they're a family of five, and we can bet that a romantic night out was just what the couple needed to really soak up those island vibes.
