Secret Santa (song)

"Secret Santa" is a song by American singer Gwen Stefani for the 2018 reissue of her fourth studio album, You Make It Feel Like Christmas (2017). It was written by Stefani, Justin Tranter, and busbee while production was handled by busbee and Eric Valentine. The song was sent to Italian radio stations for airplay on November 30, 2018 as the second single in Italy and the album's third overall. It serves as one of two previously unreleased original tracks on the reissued album. "Secret Santa" is a Christmas pop ballad accompanied by an acoustic guitar and castanets. It contains flirtatious lyrics and metaphors that reference the Christmas tradition of Secret Santa.

Critically, "Secret Santa" was noted as an adult-oriented Christmas song; Stefani compared the song to the 1953 single "Santa Baby". One music critic felt it helped enhance the parent album's track listing and was a Christmas crowd pleaser. In the United States, "Secret Santa" was the deluxe edition's most successful song on Billboard's Holiday Digital Song Sales component chart. It debuted and peaked at number 17 in November 2018 and became one of sixteen consecutive top 40 entries for Stefani. Italian singer-songwriter Tiziano Ferro released a cover of "Secret Santa" to his Instagram account on Christmas Eve in 2018.
