Megan Thee Stallion is the face of Dunkin’s new “Dunk N’ Pump” ad campaign launching January 7, 2026, as the coffee and beverage chain introduces Protein Milk and Protein Refreshers to its winter menu. In the 60-second spot, the three-time Grammy Award-winning rapper channels an ’80s workout vibe, stepping into a Jane Fonda-inspired role as “Pro-Tina” while leading a jazzercise-style routine set to an original track created for the spot. As part of the campaign, Megan delivers playful lyrics including the line “All of your exes gonna want you again,” tying in the energy of the workout with promotion of the new Mango Protein Refresher drink she helped design.

The Mango Protein Refresher, made with Dunkin’s new Protein Milk, joins a lineup of protein-enhanced beverages now available at Dunkin’ locations nationwide. Protein Milk adds 15 grams of protein to drinks and can be mixed into coffees, matchas and other Refreshers without altering familiar flavors, according to the brand’s announcement. Other menu items featuring Protein Milk include the Strawberry Protein Refresher, Caramel Chocolate Iced Protein Latte, Almond Iced Protein Matcha Latte and an Iced Protein Latte with Sugar-Free Vanilla.

Megan’s involvement in the campaign arrives amid her expanding business footprint, which recently included the opening of her own Popeyes franchise in Miami. Through her collaboration with Dunkin’, she brings her influence to the food and beverage space with a promotion that merges fitness-themed visuals, nostalgic style elements and new product offerings for the chain’s winter seasonal push.
