Signing up to a reality show means opening yourself up to criticism, especially when you're a member of the cast of Teen Mom 2. But there's a line between reasonable commentary and outright cruelty, and it has been crossed. Big time. After seeing Jenelle Evans talk about buying dope on TV, they're telling her to kill herself.

America, are you listening to yourself? You might think Jenelle Evans is a bad seed, but you've just gone way past anything she's done on MTV.

Teen Mom 3 hasn't even gotten its air date, and already one of its stars has learned the drawback to being famous. Brittany DeJesus just learned the definition of "private" for reality stars. Twitter? Is definitely not private!

DeJesus is sister to Briana DeJesus, one of the four moms set to be chronicled in the second spin-off from the original Teen Mom. She played a critical role in her sister's 16 & Pregnant episode because she too got pregnant as a teenager. Unlike her sister, however, Britt chose an abortion, and the dichotomy between the two girls' paths has been celebrated as an important lesson that can come from featuring them both on Teen Mom 3.

It has to be hard being Kailyn Lowry. Every time the Teen Mom 2 star turns around, someone else is talking smack about her. You could call it the price of fame, but when the smack talk comes from her own co-stars, you can't blame Kail for fighting back.

And boy did she ever. The topic? Kail's supposed pregnancy.

If there's one sure sign that Teen Mom mania has swept America, it's the speed with which Farrah Abraham's memoir was snatched off shelves. Now another star of the reality series is talking authorship, and we can hardly wait to hear what she has to say. Just don't expect Kailyn Lowry to walk us back down the Teen Mom path, m'kay?

In fact, when the reality star sat down with The Stir a few months back, the details she shared make her future book sound even more inspiring than the Kailyn we see struggling to get it right on TV.

It's happened. Jenelle Evans has finally managed to completely shock us. The Teen Mom 2 star is ... get this ... pregnant. Yes, pregnant, as in there's a bun in that oven. As in Jace is going to have a half-sibling. As in the woman who does not actually have custody of the child who exists in this world is going to pop another one out!

Maybe the Mayans were on to something? The world didn't end, but there is this ...

Big news out of the Teen Mom world! 16 & Pregnant star Kristina Robinson Head has given birth! The girl whose story broke our hearts on the MTV reality show has bounced back from the tragic death of her first son's daddy in a swimming accident to bring a new little guy into the world.

We were in desperate need for some happy news after the cryfest that was her episode, and these days Kristina is married to a new guy -- TJ Head -- and he's dad to the new little boy. So now for the big question. What did they name him?

Here we go again! Mackenzie Douthit, one of the four young women set to star in the upcoming Teen Mom 3, is engaged. Or should we say engaged again?

Douthit has managed a feat uncommon among Teen Moms -- both stars of the show and out here in the real world. The cheerleader who got pregnant because she worried that birth control would make her fat has managed to keep up a relationship with boyfriend Josh McKee, father of son Gannon. In fact, the couple was already engaged during their episode of 16 & Pregnant.

So why was Douthit posting on Twitter this week that she just said yes?

Whitney Purvis is in trouble again. The 21-year-old was featured on the first season of MTV's 16 & Pregnant and has had a rough go of it recently. For starters, she was pregnant at the same time as her mom. Then her mom was arrested for marijuana and meth possession. Then Whitney was caught stealing a $16 pregnancy test from Walmart, and now, she and boyfriend/baby daddy Weston Gosa, 23, have been arrested for attacking a laptop. No no, you read that right. They attacked a laptop.
