Michelle Duggar, the matriarch of the popular Duggar brood featured on TLC's '19 Kids and Counting,' has miscarried. According to People, Duggar recently had a routine check-up and the doctor could not find her 20th child's heartbeat.

The 45-year-old reality star was in her second trimester.

"After the appointment, we came back home and told the children," Duggar told People. "We had just been talking about baby names last night and they were getting excited about naming a boy or a girl. It has been a real sad disappointment."

The Duggars got to experience a little bit of Scottish culture when the latest installment of '19 Kids and Counting' (Sunday, 8PM ET on TLC) -- soon to be known as '20 Kids and Counting' as the Duggars recently announced on 'Today' that Michelle is expecting again -- saw the entire clan fly off to Scotland.

Their clan was so impressive that the organizers of the festival they were at redubbed them the MacDuggan clan. And while everyone embraced the fellowship and fun of the day, Jim Bob was a little reluctant to fully get into the spirit. They got him into a kilt, but the get-up looked rather silly with the ends of his jeans sticking out of the bottom.

Yesterday Michelle and Jim Bob Duggar announced on live television that they are expecting their 20th child together. Perhaps unsurprisingly, this has provoked criticism of the couple's lifestyle choices and their decision to proceed with such a potentially high-risk pregnancy given their already large family.

So why can't the couple stop having babies? The Internet rumor mill's been working overtime, and theories being bandied about include: Is Michelle addicted to being pregnant? Do they procreate to get attention? Are they making too much money from their reality show to give it up? Or, are they, as Michelle told Ann Curry yesterday, just staying true to their motto of "There's always room for one more?"

Now Michelle -- who has suffered twice from pre-eclampsia -- defended her decision to have another child, telling 'People' that if the prospect of potentially life-threatening prenatal complications were going to deter her, then "we would have stopped back with our second birth. ... There are many women who have experienced pre-eclampsia and have gone on to have more children."

Not even the threat of pre-eclampsia or premature birth can slow down Michelle and Jim Bob Duggar in their quest to expand their already huge family: They announced this morning on 'Today' (weekdays, 7AM ET on NBC) that they are expecting their 20th child together.

Telling Ann Curry that she's three and a half months pregnant, 45 year-old Michelle said "We're due in April and we're just thrilled!" Ever the joker, Jim Bob quipped "We don't know how it happened!" Michelle added, "We are so excited. I was not thinking that God would give us another one, and we are just so grateful." The couple had hinted last night on their blog that they'd be making a "special announcement" this morning, but many assumed it would be about another grandchild.

When Curry asked the question that most of us are thinking -- WHY?! -- Michelle said they live by the motto "There's always room for one more." Plus, as Jim Bob says, one kid just moved out to start his own family so there was space available in Casa Duggar.

Watch the happy couple's announcement after the jump.

Well, we need to thank the Duggar family once again for saving the human race. Michelle Duggar, previous mother of 17 children and current star of TLC's 17 Kids and Counting, has given birth to her 18th child. Lucky for us it's another girl who, many decades from now, will help replenish the population after the ice caps melt.

Jordan-Grace Makiya Duggar entered this world earlier this week, via C-section, at a healthy 7 pounds, 3 ounces. She was due in early January, but the baby's health was at risk due to her being transverse in the womb. Jordan-Grace now joins her seven sisters and 10 brothers (with names all starting with a 'J') in keeping the world population safe after the inevitable alien invasion that will probably wipe half of us out.

By the way, if you can't wait until next year to see the birth of Jordyn-Grace, you'll be happy to know that TLC will be airing a special on the baby's arrival soon. Very soon. As soon as next Monday, actually. 17 Kids and Counting: And Baby Makes 18 will air Monday at 9:00 pm on the network.

Family and the workplace -- two constants in everyday American society. They are the places where we spend most of our lives. Sometimes we spend more time at one over complaints of the other. Other times, we barely want to spend time at either location.

Because these are so important to many people across this country, it made sense that television would delve into both of these environments during the Reality Revolution. However, since a 60-minute show about a senior technical analyst sitting in his four square-foot cube was not likely to draw in the audience, the reality shows that were created focused on those families and workplaces that were a tad more unique. Thusly, shows were created around well-to-do families, celebrity families, or families with multiple children, while workplace shows dealt in tattoos, motorcycles, hair styling, and house-flipping.

Coming in later than the game operas and relationship shows, these family and workplace programs ushered in a new phase of the Reality Revolution and set the stage for the future of reality programming.
