After three years, numerous personnel changes, a signing to Mom + Pop Music, and a switch to New West Records, Rose released her third album.

[11] The album, Loner, was co-produced by Rose and Paul Butler of The Bees,[12] and represented a radical shift away from the musical style of her previous work, blending pop and alternative rock elements, and incorporating prominent synthesizers throughout.

Notably, this album also saw a change in lyrical tone, incorporating a number of overtly humorous, sarcastic, and satirical songs.

The video, which was directed by Amanda Speva, features Abby Pierce as the titular character, depicting Jeannie moving into a new home, performing a dance routine with the movers, and preparing a rainbow Jell-O cake.

[16] On January 7, 2020, Rose announced a new album called Superstar, releasing a single and a music video for the song "Feel The Way I Want".

"[19] The album Superstar was released on March 6, 2020,[20][21] and Caroline Rose made her television debut on February 24, 2020, performing "Feel The Way I Want" on Late Night with Seth Meyers.

[25] The film, "a single continuous narrative of disintegrating time loops, splintering romantic and existential relationships and intricately choreographed long takes",[26] was released in June, 2024.
