They are headed for an even 20!  Jim Bob and Michelle Duggar, stars of TLC's 19 Kids and Counting, announced this morning on The Today Show that they are expecting child #20.  From, "We are so excited," says Michelle, 45, who is now three-and-a-half months into her pregnancy and due in April.  "I feel good.  I am past the sickness stage now."

The couple, who are parents to 19 children ranging from age 2 to 23, have been answering a lot of pregnancy questions from their fans.  Michelle is under the care of a high-risk pregnancy doctor and is being very cautious, eating a lot of protein and green vegetables and abstaining from caffeine.

The season 5 finale of 19 Kids and Counting airs at 9pm tonight on TLC.  There is also a special, The Duggar's World Tour: Scotland & Ireland, showing a newly pregnant Michelle traveling to Europe with the whole family.  The special premieres November 13th, at 8pm on TLC.
