81-year-old goes viral for reviewing Sabrina Carpenter's new Dunkin' drink; Sabrina responds

Sabrina Carpenter recently partnered with Dunkin' on a new drink called Sabrina's Brown Sugar Shakin' Espresso, but she probably never thought the "influencer" who'd get the beverage a lot of attention would be an 81-year-old grandmother.

Carol Chapman posts on TikTok as "Grandma C," and often posts videos reviewing coffee and doughnuts from the front seat of her car. She reviewed the Brown Sugar Shakin' Espresso a few days ago, and praised its "strong coffee flavor" and creaminess. However, she admitted that she didn't know who Sabrina was and "had no idea" what the song had to do with the "Espresso" singer.

According to People, after Chapman posted the video, she started getting messages from her family telling her that the video had gone viral — currently it's up to more than 900,00 views and 1,200 comments. One of those comments is from Sabrina, who wrote, "I love you grandma C." Chapman responded, "I love you."

"I couldn't really believe it," Chapman tells People about Sabrina's reaction. "Then all my granddaughters were calling and texting, so I figured it was true."

And now, Chapman's happy to report that she knows all about Sabrina and her songs.

"First I found out about the song 'Espresso,'" she says. "Then I listened to it. Then on my next TikTok I told people who she was and I said the song made me happy and made me feel good."

"I have listened to all the [Sabrina] songs I could get," she adds. "Saturday night I was looking on Netflix to find something to watch and her Christmas special came up, so I watched it. Now I like her so much as a singer and if she ever appears near me, I would love to see her."
