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

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.

These tracks were "Hold Me Oh My Darling" (on 1967's United) and "I Can't Believe You Love Me" (on 1969's Easy).

"This Old Heart of Mine (is Weak for You)" is a remake of the 1966 Isley Brothers' hit by the same name.
