After being rushed to the hospital last weekend for gallbladder issues, Michelle Duggar, star of TLC's 18 Kids and Counting, says she is "feeling much better."

She and her husband Jim Bob Duggar offered fans an iPhone video update from the Arkansas hospital where she is currently recovering.

"The gallstone has kind of calmed down... blood pressure is still getting regulating, and the baby sounds good," she told fans. "So we're sort of waiting to see what happens."
