Maci, Amber and Catelynn all found fame alongside Farrah on MTV's 16 & Pregnant, before later starring in Teen Mom, and they have returned to their roots to film brand new episodes.
Teen Mom Original Girls catches up with the young mums six years on and, at first, it was only going to feature the lives of Maci, Amber and Catelynn.
However, last month bosses confirmed that Farrah had signed up to the new series and, at the time, sources claimed that the other girls were not happy.
Well, judging by the new trailer, the insiders were spot on!
In the short clip, producers are shown breaking the news to the girls that Farrah is returning.
A member of the crew can be seen telling Catelynn and her fiancé Tyler Baltierra: "The decision has been made to bring back Farrah." The couple scream with shock.
Amber, meanwhile, simply moans, "Oh my God", while a very unimpressed Maci asks: "You're lying?" She then adds: "You guys can leave now. This is over."
Farrah is then shown walking through an airport, telling the cameras: "We're ready to rock this!"
Since they last appeared in front of the cameras, Farrah has made quite a name for herself. She has filmed two sex tapes and recently released a trilogy of erotic fiction.
The mum-of-one has also changed her appearance dramatically with the help of cosmetic surgery. Last month, Farrah shared pictures of herself with huge lips following an allergic reaction to fillers.
Teen Mom Original Girls airs in the US on 21 March, however there is not yet a transmission date for fans in the UK.
Reveal has contacted MTV UK, who have promised to let us know as soon as they do!
