"Bed Chem" is a song by American singer Sabrina Carpenter from her sixth studio album, Short n' Sweet (2024). The song, co-written by Carpenter with Julia Michaels, Amy Allen, John Ryan, and Ian Kirkpatrick, is a blend of pop, synth-pop, disco, and R&B with a retro vibe influenced by artists like Christina Aguilera. The lyrics center on the theme of intense attraction and sexual chemistry ("bed chemistry") between Carpenter and a man, widely interpreted to reference her then-boyfriend, Irish actor Barry Keoghan. The song's production features synthesizers, a G-funk whistle, and a catchy, upbeat tempo of 95 BPM in the key of B minor. "Bed Chem" was released as the fourth single from the album on October 8, 2024, and it achieved commercial success, debuting at number 14 on the Billboard Hot 100 and reaching the top ten in several countries including Australia, Ireland, and the UK. The song was certified platinum or double platinum in multiple regions. Its live performances include an edgy set on Carpenter's Short n' Sweet Tour and a memorable medley performance at the 2025 Brit Awards, featuring a large pink bed stage prop and choreography that emphasized the song's sultry nature. The lyrics vividly describe a romantic and sexual encounter, filled with playful, candid, and suggestive phrases, reflecting Carpenter's aim to capture a sexy but lighthearted tone. The song's title and concept originated from Carpenter's experience with her best friend about "really good bed chem," later adapted to describe chemistry with a romantic partner in this track.
