It was probably for the best that Jenelle went to the Ke$ha concert. After all, she does have really good dance jams.

Being a felon is definitely illegal. You're just so wrong on so many levels here, Kieff.

Chelsea needs to get over Adam and find her Prince Charming. We have a few guys in mind that would be perf. for Chels.

Oh, and Chelsea is officially a high school grad! Woo hoo!

Kail has completely moved on from Jordan. Thank goodness…he was weird.

It was a bumpy ride for Leah to get through her divorce from Corey.

It's probably because her new hubs, Jeremy, is kind of Corey's twin. Whatevs, we love Jeremy so it's all good.

Jenelle has run into some drug problems this season. Which her mom, Babs, is having a hard time understanding.
