The singer and her husband Todd Bray are due to welcome their first child imminently, but the sick star reveals she spent all of Thursday (12Mar15) under doctors' care amid fears for herself and the welfare of her unborn son, who she plans to name Ryman Marshall.

On Friday (13Mar15), she shared a photo of an intravenous drip inserted into her left hand on Instagram.com and revealed all about her health emergency.

In the accompanying caption, she wrote, "My Poor lil puffy hand... We had a little scare and a very rough day yesterday...

"Ended up in the ER ALL day with pre-term contractions caused by severe dehydration, possibly brought on by a virus... we are getting much better...

"Just trying to make sure to MAKE myself take it easy now, and fully recover. I finally felt good enough to eat some real food today, and got to take an oh so beloved bath... So things are looking up here at the Bray household."

The parents-to-be wed last summer (14).
