Sabrina Carpenter References ‘Saltburn’ Bathtub Scene in Coachella Outro

Sabrina Carpenter incorporated Barry Keoghan into her latest outro … referencing a scene from his flick “Saltburn” — and leaving fans with a really raunchy line.

The singer-songwriter took the Coachella stage Friday and finished it off with her hit song “Nonsense.” If you don’t know, the track ends with Sabrina saying a couple lines — usually sexual — and she changes it up from performance to performance.

Friday night’s lines … “Made his knees so weak / he had to spread mine. He’s drinking my bathwater like it’s red wine / Coachella, see you back here when I headline!”

It’s a pretty clever line … and, if you check out the clip, fans go crazy for her bathwater lyrics — ’cause it’s a clear reference to her man Barry Keoghan’s “Saltburn” movie.

Also, peep the shirt Sabrina’s wearing with the Jesus reference on it … another person known for turning water to wine — just sayin’.

If you haven’t seen “Saltburn” … Barry’s character laps up dirty bathwater left behind after Jacob Elordi’s character washes himself — oh and there’s semen in the water as well just BTW.

Sabrina’s taken the sexual nature of the scene and twisted it here … and, ya gotta think BK absolutely loved it. After all, he’s on of SC’s biggest fans!

Remember … Sabrina gave Barry a little wave at her performance during Coachella’s first weekend — and, he seemed totally jazzed about getting the shout-out mid-performance.

They’re also out in public together a bunch these days … earlier this week, TMZ obtained exclusive photos of the dynamic duo just hanging out in Disneyland — so, it seems it’s getting super serious.
