Yours Faithfully is the fourth and final studio album to date by American R&B singer Rebbie Jackson.

"Yours Faithfully" is a song by American singer Rebbie Jackson. A mid-tempo R&B jam written and produced by Eliot Kennedy and Pam Sheyne, it is the title track from her fourth album, Yours Faithfully, and it was released as its first single.

Making a comeback to the music scene after 10 years, Jackson signed to her brother Michael's label MJJ Music, which released the album and the single at the beginning of 1998.

Despite Jackson promoting the release in the USA and Europe, and receiving mostly favourable reviews, the single failed to have much success, peaking at #76 in the USA R&B charts, and #76 in the UK charts, this being Jackson's only chart entry in the UK.

In the UK, the single was released as a two-part CD. The b-side was the original extended version of Jackson's 1984 hit Centipede.
