The pop star has teamed up with bosses at New York's fabled Serendipity restaurant to create the Cookies & Cream Remix, made with pink vanilla ice cream, crunchy cookie bites, and fudge.
The new treat will be available from 28 August - the same day as the two acts' new single.
"Growing up and loving the iconic Serendipity restaurant, I couldn't be more excited to become a partner in their expanding brand," Selena said in a statement. "For the Cookies & Cream remix, I wanted to put my own personal spin on this classic flavor by making it with pink vanilla ice cream as a nod to my girls BLACKPINK and celebrate our new song 'Ice Cream'."
In a video she posted online on Monday, August 24, Selena savours her tasty creation and tells fans, "Basically it's heaven and every bite is delicious."
Tubs of the Cookie & Cream Remix feature a cartoon version of Gomez.
