Taylor Swift may be humming a different tune during her next performance of "All Too Well."

The pop star praised Ryan Gosling and Emily Blunt's cover of the "Red" era track on "Saturday Night Live." Swift giddily offered her stamp of approval in an Instagram story on Sunday.

"All Too Well (Ryan and Emily's Version)!!! Watch me accidentally catch myself singing this version on tour. This monologue is everything," she wrote under a clip from Gosling's "SNL" opening monologue.

"I left my rollerblades in that big pink house, but I still got that fur coat and I'll wear it right now," Gosling sang at a piano, going on to declare, "I was just Ken, and now I'm just Ryan."

Blunt, co-starring with Gosling in the upcoming action comedy "The Fall Guy," joined him on stage to chastise him for still obsessing over Ken before acknowledging she also misses her character, Kitty, from "Oppenheimer" − which Gosling described as an "inferior movie" to "Barbie" in a continuation of their Oscar roast. In a duet, Blunt and Gosling both sang about their "Barbenheimer summer" and wished their characters farewell as dancers in "Barbie" and "Oppenheimer" costumes took to the stage.

Gosling knows the real lyrics to the Swift track "All Too Well," which made an appearance in a February "Fall Guy" Super Bowl 58 ad, also featuring Blunt.

The fast-paced trailer includes a scene with the "Barbie" actor sitting in a parked car solemnly mouthing the words before Blunt knocks on the window, startling a crying Gosling.

"What are you doing?" Blunt asks.

"Just chilling down," Gosling responds.

"Have you been crying to Taylor Swift?" Blunt says.

"Doesn't everyone?"

As Swift and Gosling seem like big fans of each other, it was only a matter of time until they worked together. Both have worked with choreographer Mandy Moore, whose credits include the Eras tour, "La La Land" and Gosling's "I'm Just Ken" Oscars performance.
