Lindsay Lohan is bringing the holiday cheer with a Mean Girls costume throwback and a dirty soda.

The new reigning queen of Christmas and Falling for Christmas star (buh-bye Candice Cameron Bure), Lohan got into the season’s spirit in her new “Pilk and Cookies” campaign for Pepsi. It’s a trend that has grown in popularity on TikTok of mixing soda with milk or cream (spoiler alert: it’s delicious).

In the video, Lohan is making herself a holiday drink, dressed in her iconic Jingle Bell Rock costume.

As she pours the soda into the glass she declares it “nice,” then she adds the milk and says “naughty.” The video ends with Lohan naming the drink: “Pepsi and Milk — Pilk!” she says with a smile.

In a second ad, Lohan sneaks downstairs to discover Santa has left her a tasty treat, a plate of cookies, and a glass of pilk. “That is one dirty soda, Santa,” she says after taking 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.”
