Lindsay Lohanis the latest celebrity to hop on the dirty soda bandwagon.
TheFalling for Christmasactor is getting into the holiday spirit with Pepsi as she stars in a new festive campaign called “Pilk and Cookies.” Short for Pepsi and milk, the beverage is a twist on the dirty soda,a drink popular on TikTokthat combines soda with milk or cream.
In the commercial, Lohan gets a surprise from Santa Claus as she tiptoes down the stairs of a cozy home in her red flannel pajamas and Santa hat. She sits on the couch and finds that Santa poured Pepsi and milk into a glass next to a plate of cookies.
“That is one dirty soda, Santa,” she says as she takes a sip.
“Partnering with Pepsi to announce Pilk and Cookies has been an incredible experience,” Lohan said in a release. “As someone who loves the holiday season and embracing new traditions, I was thrilled to have a little bit of fun with Pepsi and their take on the dirty soda. For people learning about Pilk for the first time, I won’t lie to you when I say I was a bit skeptical when I first heard of this pairing, but after my first sip I was amazed at how delicious it was, so I’m very excited for the rest of the world to try it.”
Olivia Rodrigohelpedpopularize dirty sodaon social media. Last December, the pop starposted an Instagram phototo her feed holding a cup fromSwig, a soda shop that specializes in making dirty sodas.
Since then, the unconventional beverage — which consists of a soda mixed with creamer or half and half, flavored syrups, and lime juice — has popped up all across social media.
The first two seasons of Rodrigo’s breakout show,High School Musical: The Musical: The Series, were filmed in Utah, where the fizzy-creamy drink has been wildly popular since the 2010s. They’ve become a mocktail-esque mainstay in the state likely because Utah has a large Mormon population, who don’t typically drink alcohol and instead enjoy these sugary-sweet drinks, according toVice.
Flavors have since evolved since the early craze of dirty sodas. The shop Rodrigo visited offers an expansive list of fun menu items, including Naughty & Nice, a blend of Dr. Pepper, English toffee and half and half, and more fruity flavors like the Beach Babe, which mixes Mountain Dew, raspberry, peach and vanilla cream.
