In case you've spent your entire Christmas vacation catching up on Season 2 of MTV's reality TV show, Jersey Shore, there's something you should know: MTV also has another reality TV show that's made almost as much noise as the Shore in 2010—so you might want to take a couple extra days off.

There's no Snooki or Situation, no fist-pumping and certainly no boozing going on during this reality TV show. Instead, MTV's Teen Mom—a show that was birthed (pun very much intended) as a spin-off of another popular MTV show, 16 and Pregnant—took the boob tube by storm this year and has turned into such a hit MTV is already planning another brand-new season of it.
