As an aspiring singer-songwriter, Olivia Rodrigo has always looked up to Taylor Swift from a young age, even calling herself "the biggest Swiftie in the whole world" in a January 2021 interview with Apple Music's Zane Lowe (via Billboard). Needless to say, the young singer was thrilled when Swift commented on her Instagram post, in which Rodrigo said she was "a puddle of tears" after "Drivers License" had her landing next to Swift on the iTunes charts. Swift wrote in response, "I say that's my baby and I'm really proud" — a message that had Rodrigo fangirling as she commented back (via Seventeen), "Crying like a baby! Thank you for everything u do!!!!!"

"I checked my phone and she commented on my photo and I just about died ... just about died," Rodrigo recalled on the radio show. "Literally, I've looked up to her as long as I can remember, so it was so sweet of her to do that."

Looking back at Rodrigo's history, it's pretty obvious that the up-and-coming artist is a huge Taylor Swift fan. In February, she included multiple songs by Swift in a self-curated playlist of 18 favorite songs that "shaped her into who she is today," revealing that "Picture to Burn" — released off of Swift's debut album in 2006, when Rodrigo was just 3 years old — was her first favorite song ever (via Billboard).
