Mexican Pizza: The Musical aired on the social media site on May 26 to mark the return of the previously discontinued and much-loved item to the fast food chain’s menu.
Doja Cat has been a high-profile supporter of the Mexican Pizza, writing a “contractual” rap for Taco Bell in 2020 when the item was taken off the menu. “I will end you if you ever dare to go discontinued,” she rapped in the jingle, adding: “This ain’t even Mexican food.”
The seeds of Mexican Pizza: The Musical were then sown when TikTok comedian Victor Kunda took the jingle and created a parody version of a musical about Mexican Pizza starring Doja Cat.
Elsewhere, last month Dolly Parton was awarded $100million (£84.8m) by Jeff Bezos to put towards charitable causes after the Amazon founder revealed plans to give away most of his fortune.
The country music icon will be able to donate the money to charities of her choice, after it was announced that Bezos has pledged to give away the majority of his $124billion net worth (£105billion).
