Taylor Swift has always been a theatre girl, and these new throwback pics of her as Sandy in a local Grease production are enough proof.

The world now has enough proof of Taylor Swift being a thespian thanks to Tobin Mitnick. On Thursday, the actor and comedian shared a thread of photos on Instagram, throwing back to the time when Swift played Olivia Newton-John’s Sandy Olsson in a local production of Grease.

Mitnick was her co-star back then as he starred as her love interest, Danny Zuko – played by John Travolta in the ‘70s musical comedy. Captioning the post, “Thank you mom for digging these pics of @taylorswift and I harmonizing like buttah on summer nights twenty five years ago out of storage.”

The third picture especially caught Swifties’ eyes. It featured the Anti-Hero singer sporting a huge wig curly blonde locks as she must’ve channelled her inner Grease lead character energy.

Tobin Mitnick concluded his caption with a nod to Taylor’s current boyfriend Travis Kelce, the tight end of Kansas City Chiefs: “Also trav the note is an f-sharp if youre interested. June 2000”, Tobin posted three snaps of their younger selves.”

The comments section of Mitnick’s carousel post has been especially eye-catching now that fans have spotted Taylor Swift in Grease. Reactions such as “I NEVER IN A MILLION YEARS SAW THIS CROSSOVER COMING”,

“This is an insane crossover”

“This was not the mashup I was expecting today”

Social network flooded the post with awestruck admiration.

Swifties never miss an opportunity to praise their favorite pop star, as evidenced by comments such as “This just serves to further demonstrate that Taylor was always THAT girl.

“She performed well, and I can see why she is ruling major stages throughout the world.”

However, some fans of Taylor’s Sandy outfit and wig couldn’t get enough, saying things like:

“Ok, but Taylor’s wig is cracking me up,”

While another made the very funny joke, “Why wasn’t this part of the eras tour?”
