Hayley Williams says Taylor Swift's mom introduced them because Swift didn't have many musician friends her own age

• Hayley Williams spoke about her friendship with Taylor Swift on "The Tonight Show Starring Jimmy Fallon."
• Williams revealed that Taylor's mom, Andrea Swift, introduced the two singers when they were both 19.
• Andrea told Williams, "Taylor doesn't have a lot of friends her age that do music."

Hayley Williams opened up about her friendship with Taylor Swift during a recent appearance on "The Tonight Show Starring Jimmy Fallon."

Williams and Swift both moved to Nashville as teenagers to pursue careers in music. Many fans know they met as 19-year-olds in 2008, when Williams' band Paramore and Swift were both nominated for best new artist at the Grammys.

However, many fans weren't aware that Swift's mom, Andrea Swift, was actually the spark for their initial meeting.

"So, we were at some Grammy party," Williams told Fallon. "It was actually Timbaland's Grammy party. Huge. I was very nervous."

"A woman came up to me and she said, 'I'm Taylor Swift's mom and, you know, Taylor doesn't have a lot of friends her age that do music. And I would love to, like, you know, introduce you guys or get your number,'" Williams continued. "So Andrea, the legend that she is, she connected us."

The two women have remained close. Swift tapped Paramore as one of the opening acts for her blockbuster Eras Tour, and Williams is featured on Swift's latest album, "Speak Now (Taylor's Version)."

Back in February, Williams also revealed that Paramore's song "Running Out of Time" was partially inspired by an early interaction with Swift.
