It's interesting how all the four divas of the 90s (Janet, Madonna, Whitney and Mariah
) had #1 hits together only in 1990. They ruled for 15 weeks together. Pick one.
1. Vision of Love - Mariah Carey (4)
2. Vogue - Madonna (3)
2. Escapade - Janet Jackson (3)
2. Love Takes Time - Mariah Carey (3)
5. Black Cat - Janet Jackson (1)
5. I'm Your Baby Tonight - Whitney Houston (1)
*Edit: It seems they did it in 1991 as well: Janet with Love Will Never Do, Madonna with Justify My Love, Mariah with Someday, I Don't Wanna Cry and Emotions, and Whitney with All The Man That I Need
