"Fall in Love at Christmas" is a holiday song by American singers Mariah Carey, Khalid, and Kirk Franklin.

[3] On November 1, Carey officially announced the song, which was scheduled for release on November 5, through a 30-second preview, revealing the song to be a romantic R&B-tinged ballad, with Carey and Khalid singing together in the chorus and a gospel inspired choir led by Kirk Franklin.

Vulture writer Rebecca Alter called the song an "extremely smooth duet with Khalid" praising their harmonizing.

[8] Gotrich also praised Khalid's vocals stating that "the 23-year-old R&B singer knows no one can outdo Carey, so his harmonies add just the right amount of tinsel".

[7] Throughout the video, Carey "spreads the cheer with Khalid and gospel great Kirk Franklin in the clip that finds the three hanging in their PJs in Mariah's living room as they croon over the track's finger-picked guitars and subtly chiming sleigh bells".
