Alter Ego is the upcoming debut solo studio album by Thai rapper and singer Lisa.

[4] Lisa first teased the title of her upcoming album in the music video for the single "New Woman" in August, in which multiple women were shown reading a magazine named Alter Ego.

[5] In an interview for her Billboard cover story in November, she shared that she was working hard on the album "trying to figure it out, the track list and everything, what I can change in there" and played some of the unfinished songs for the reporter.

[7] The five "alter egos", named Roxi, Kiki, Vixi, Sunni, and Speedi, each correspond to various tracks and feature on album versions with their own cover art.

"[7] The album's promotional campaign uses a five-point star as a recurring emblem to represent the five alter egos, while its trailer video features the rapper in five locations, one for each persona: a black rock structure, an outer-space catwalk, an enchanted garden, a green laser-beam motorcycle track, and a volcanic red runway.

[10] The second alter ego Sunni, deriving from "Moonlit Floor (Kiss Me)", is a free-spirited French speaker with brown curly hair who has a "je ne sais quoi for sun-kissed days and sea-breezy nights".

[15] The teaser's caption revealed one letter of the project's title, while a countdown also appeared on Lisa's website due to complete one week later on the 19th.

[28] She presented both songs and "Moonlit Floor (Kiss Me)" before its release as a headliner for the Global Citizen Festival in New York City on September 28.

[31] On New Year's Eve, Lisa performed "Rockstar", "New Woman", and the "Santa Baby" remix of "Moonlit Floor (Kiss Me)" as a headliner for Amazing Thailand Countdown 2025 in Bangkok.
