The Gospel sensation has been out and about lately performing everywhere from the 2011 Soul Train Awards to events on the west coast.

Erica said in a statement today, "This was a very hard decision for me. I'm accustomed to pushing myself beyond my doctor's recommendations during my pregnancies, but after having seen my sister, Tina, deal with a premature birth as a direct result of an exhaustive pace, I recognize how real this is. Although my passion told me to push on as usual in these past months, my wisdom, as of my last week's doctor's visit, told me to take care of myself and my new baby-to-be."

Sister Tina adds, "Our commitment to our passion of music and our fans is without question, but allowing wisdom, common sense, and our commitment to family take the lead at this point is necessary."
The duo plans to return to performing in the spring and is looking forward to rescheduling their Christmas tour dates for 2012. Erica is scheduled to give birth in February.
