Sisterhood. Family. Mega Gospel music careers. For sisters Tina and Erica Campbell (who are the lovely ladies of Mary Mary) live anything but a normal life. Now they’re adding “reality show stars” to their already impressive resumes. Their new show – which is appropriately named Mary Mary and has their latest single “Go Get It” as its theme song – premieres this Thursday (March 29th) on WE Tv at 10/9c.
