Mary Mary is a Grammy-winning gospel duo comprised of sisters Erica and Tina Campbell. The sisters are busy career women as they tour the country promoting their album and walking down Hollywood red carpets. But out of the spotlight, they are wives and mothers trying to balance family life with their superstar lifestyles. Erica and Tina's other sister, Goo, is also the sisters' stylist. The trio often butts heads, usually because Goo thinks she is underappreciated and underpaid. Also in the mix are Erica and Tina's husbands, Warryn and Teddy, respectively, who are also in the music business.
