Princess Cruises’ newest ship Star Princess has been christened by godparents Camila and Matthew McConaughey with a giant bottle of Pantalones Organic Tequila.

The ceremonial maritime tradition dating back centuries usually involves Champagne, but when your godparents are in the tequila business …

“It’s the first time ever, ever, in the history of the tradition that it will be a Pantalones tequila bottle,” Camila told PEOPLE magazine.

“Reposado, our favorite,” adds Matthew.

The naming ceremony took place in the ship’s Princess Arena, with live entertainment that included a special performance by nine-time Grammy Award-winning singer songwriter Sheryl Crow.

“It’s an honour to follow in the footsteps of past godparents and welcome Star Princess into the Princess fleet,” said Camila and Matthew McConaughey.

“We are excited to share this moment with the guests who step aboard – coming together with family and friends, making new memories, and sharing a Pantalones cocktail, or two.”

The McConaugheys organic tequila brand, Pantalones is featured across the Princess fleet, including in the fleet’s popular 24K Gold Margarita and the Love Line Premium Liquors Collection.

Princess Cruises President Gus Antorcha said: “Star Princess is a stunning reflection of our legacy and our future – bringing together incredible design, exceptional experiences, and the spirit of discovery our guests love. We’re grateful to Matthew and Camila McConaughey for joining the Princess family and know their warmth and infectious spirit will always be felt throughout Star Princess.”

Camila and Matthew McConaughey join an illustrious group of Princess Cruises godparents including Princess Diana; Catherine, Princess of Wales; Audrey Hepburn and Sophia Loren.
