Actresses Anna Kendrick and Rebel Wilson, stars of "Pitch Perfect 3" are best friends in real life. So it's fitting they co-star in "Besties," the new campaign for Splash Refresher water, which bills its beverage as a more flavorful way to stay hydrated.

Denver-based Grit is responsible for the 30-second and 15-second spots, part of a national buy running across TV and digital channels through 2025.

Flavors include kiwi watermelon, black cherry, rocket freeze (blue raspberry, cherry, and lime) and blood orange. The tagline:"Like Water. But Good." Each is made with zero sugar, zero calories and zero colors.

"When I first tried Splash Refresher Sparkling Beverage, I was like, 'Wait. Why does this feel like a holiday in my mouth?'" said Rebel Wilson. "It's bubbly, it's fun and suddenly I'm the most hydrated I've ever been."

Or as Wilson notes in the longer ad: "Splash is better than taking your bra off at the end of a long day."

The launch signals the brand has expanded to both still and sparkling options.

Kheri Tillman, chief marketing officer, Primo Brands, added: "A good friend challenges you, inspires you, and refreshes you. That's the spirit of our 'Besties' campaign, starring the ultimate besties, Anna and Rebel, who are the perfect embodiment of the lightheartedness and vibrancy of the brand."

Grit's client work also includes Arrowhead Mountain Spring Water, Beer Hug and Duke's Sausages.
