Irresistible was the only solo album for Tammi Terrell, which was released in January 1969 by Motown Records.

Tammi Terrell had a sexy, hypnotic voice and alluring sensibility that not only made her an ideal partner for Marvin Gaye, but could have resulted in substantial impact as a solo singer. This album includes her finest solo single, "I Can't Believe You Love Me,".

Due to complications with a malignant brain tumor in 1968 which caused her death in March 1970, Terrell did not record a subsequent solo album; this album compiles solo recordings Terrell made for Motown between 1965 and 1968. Two of the tracks included on this album were dubbed with vocals from Terrell's frequent singing partner Marvin Gaye to create album tracks for the duo's joint albums. These tracks were "Hold Me Oh My Darling" (on 1967's United) and "I Can't Believe You Love Me" (on 1969's Easy).
