In the now-viral video, which has over 2 million views, Eliana Shiloh re-countered her interaction with the popstar, explaining that she was short 45 cents for her coffee, when a kind stranger behind her in line said, “I got it”, handing over a $1 bill to the cashier.

Eliana turned around to thank the stranger, who was, in fact, Ms Sabrina Carpenter.

“I saw a bunch of videos during the day of her being spotted around Chicago with this umbrella and security and actual videos of her, and I really didn’t think much of it,” the TikToker said.

“I decided to go for a little walk and get some coffee,” she said.

After she had ordered, she realised she owed the barista $5.45, but she only had $5 cash on her.

“I remember that I have this $5 cash, and I’m like, ‘Wow, if I use this $5 cash, then the coffee is going to be free’ because girl math,” she said, before saying she planned to use her credit card to pay the 45 cents.

“While I’m pulling my credit card out for this 45-cent charge, I hear a voice behind me say, ‘I got it’.”

On realising that it was Sabrina Carpenter, Eliana says, “I’m in shock.”

“I have no idea what to say. Sabrina Carpenter just paid for my coffee. But something popped into my head, and I just blurted it out,” she said.

“I looked Sabrina Carpenter right in the eye, and I said, ‘That’s that me espresso’.”

Days later, the singer seemingly responded to the encounter, posting a TikTok lip-syncing to a popular TikTok clip of Jennifer Lawrence singing in the movie Joy.

“And then I go and spoil it all by saying something stupid like ‘that’s that me espresso’,” Sabrina mimed.
