These tracks are love letters of letters shimmering gold. Kali Uchis unveils Sincerely: P.S., the deluxe edition of her acclaimed fifth album Sincerely, out now via Capitol Records. Executive-produced and largely written by Uchis herself, Sincerely stands as a journal of rebirth and intimacy, shaped by her recent journey into motherhood. Adding five new tracks to her most personal body of work yet, Uchis introduces the lush and aching Pretty Promises. Featuring Mariah The Scientist, this song is a soulful meditation on desire and devotion wrapped in ethereal harmonies. The single highlights Uchis’ gift for making the intimate feel cinematic. With Mariah The Scientist, she creates another dreamlike pairing, weaving together vulnerability and strength in equal measure.

“Pretty Promises” arrives as the second exclusive duet on "Sincerely: P.S.," following September’s Cry About It! with Ravyn Lenae. That track, performed on The Tonight Show Starring Jimmy Fallon in a ballerina-box-inspired set, showcased Uchis’ flair for blending classic romance with modern artistry. Now, Sincerely: P.S. deepens that narrative with new layers of sound and storytelling. Cementing her as one of the most transformative voices in contemporary music, let “Pretty Promises” draw you deeper into Kali Uchis’ world.
