Mariah teamed up with McDonald's in 2021 for The Mariah Menu — 12 days of free food that featured a select free item each day through Christmas Eve with a $1 minimum purchase on McDonald's mobile app. “Some of my favorite memories with my kids are our family trips to McDonald's, and of course, each of us has our go-to order,” Mariah said. “Bringing together some of our favorite food from McDonald's with my all-time favorite season is a holiday wish come true.” The Mariah Menu also featured free beanies with Mariah's signature and t-shirts with a photo of her.
