With just hours to go until Sabrina Carpenter takes over SNL, the singer reminded fans to tune with an Instagram post full of backstage snapshots.

“TONIGHT,” Carpenter captioned her photo post, tagging @nbcsnl and topping it off with a red lips emoji.

The pics give viewers a glimpse at her dressing room and outfit options. There’s also a peek at what looks to be a table read or writing session, and at the actual cue card that was used filming this week’s promo spot — all at SNL‘s 30 Rock headquarters in New York City.

Saturday night (Oct. 18) marks Carpenter’s first time hosting SNL, and her return as musical guest. The “Manchild” hitmaker performed during a May 2024 episode and was featured on February 2025’s SNL50 special, for which she sang a duet with Paul Simon and co-starred in one of Marcello Hernandez’s “Domingo” sketches. (She’d already had a run-in with Domingo at one of her concerts on the Short n’ Sweet Tour, during her “Juno” bit; he was the crowd member arrested for being too hot at a Los Angeles stop.)

With a background in sitcoms, plenty of experience on the live stage and a knack for penning punchy song lyrics, Carpenter is primed to let her comedic side shine Saturday night.

As musical guest she’s promoting her latest album, Man’s Best Friend, which made its debut at No. 1 on the Billboard 200 in August.
