'Teen Mom' Season 4 the end of original four Farrah, Amber, Maci and Catelynn

There's no premiere date yet "Teen Mom," but Season 4 be the last time Farrah Abraham, Maci Bookout, Catelynn Lowell and Amber Portwood act as basic cable's poster girls for teen pregnancy. Understandable since it's hard to be the stars of a show called "Teen Mom" as you head out of your teens. Not to mention Johnny Law can really mess up a shooting schedule.

"They will continue to be a part of our MTV family," MTV assures US Weekly, "and we're thankful to these brave young women for sharing their stories and helping to make a positive impact on teen pregnancy prevention."

Which sounds like a positive sign in the direction of Farrah getting her own spin-off.

While "Teen Mom" will sunset, "Teen Mom 2" is still in play and thanks to the seemingly endless supply of "16 and Pregnant" participants, viewers can look forward to "Teen Mom 3" as well.
