MoKenStef was an American female R&B trio from Los Angeles, California, active from 1994 until 2000. The group name was a combination of the first syllable of each member's name: Monifa, Kenya, and Stefanie. They released an album, Azz Izz, in 1995, and their biggest hit was " He's Mine", which peaked at #7 on the Billboard Hot 100. It also spent one week in the UK Singles Chart in September 1995 at #70. Their second single, "Sex in the Rain", was not as successful, peaking only at #63 on the US R&B chart.
The last single was intended to be "Baby Come Close", remake of Smokey Robinson's song, for which MoKenStef recorded a remix called "I Can't Help It" (this one was a cover of Michael Jackson's song). Both, album and remix versions were released promotionally on cd and vinyl, the group also made a video for it directed by Cameron Casey, but in the end the intended single was never released commercially.
The group also did a couple of performances of "He's Mine" in 1995 on Soul Train, All That and Video Soul.
