Julia Roberts recounts on-stage experience at Taylor Swift's The Eras Tour on Jimmy Fallon's show

LOS ANGELES, CALIFORNIA: Julia Roberts, the celebrated actress, made an appearance on 'The Tonight Show Starring Jimmy Fallon' on Tuesday, December 5 to promote her new film, 'Leave The World Behind.'

However, it was her experience at Taylor Swift's The Eras Tour that she seemed most eager to discuss.

The Hollywood icon, who proudly identifies herself as a "hashtag superfan" and a "Swiftie," shared numerous candid moments with Fallon that are certainly worth a second look.

Julia Roberts is a 'Superfan' of Taylor Swift

Fallon highlighted an Instagram post from Roberts, posted after she attended Swift’s concert in June. In the post, the actress expressed her admiration for Swift, writing, "@taylorswift I Love You. Thank you for being EVERYTHING WE EVER NEEDED! Ever."

It was at this point that Roberts declared herself a "hashtag superfan" and a Swiftie, a term commonly used by fans of the pop star. And as it turns out, she has evidence to substantiate her claim.

"My Spotify wrapped was embarrassing," Roberts admitted, referring to the year-end data summaries that Spotify provides to its users. "It was not like the cool, let me share this with all my friends, it was like a, I figured as much."

Fallon, who is also a self-proclaimed Swiftie, then presented a photograph of Roberts sharing the stage with Swift and Joan Baez at a Swift concert in 2015.

Roberts later shared that she had taken her children, Phin and Hazel who were approximately 10 and 8 years old at the time, to their first major concert.

Before the show, Swift had invited Roberts to join her and others, including Baez, on stage for a dance during a particular segment of the show.

"This was, like, our first big concert. And Taylor had said before the show, you know, Will you -- There's a part in the show where, you know -- Would you like to come on stage? And I was like, Oh, I don't know." Roberts said. 

"I get very nervous. I mean, I'm so sweaty right now, words cannot describe. And so I was like, I don't know, I don't know."

"And at the time, I think Phin and Hazel were 10 and Henry was 8, and they were like, oh, Mom, you should do it. You should do it."And Henry goes, Don't do it unless you feel comfortable."

Roberts confessed that she was initially hesitant due to her tendency to get nervous and sweaty.

However, she decided to take the plunge after receiving encouragement from her 8-year-old and changing into a Swift t-shirt.

This was because she was wearing the same outfit she had worn a few days earlier on 'The Ellen Degeneres Show.'

She continued, "And then I said, Well, can I get a Taylor Swift T-shirt to wear if I go on stage? Because I was wearing an outfit that I had worn like two days before on the Ellen show."

"The whole thing was pretty surreal, and the Joan Baez part of it made it even more surreal," Roberts added.
