At the time, producers filmed several endings but eventually settled on Kristin Cavallari driving away from her on/off boyfriend Brody Jenner.
Suddenly the scenery behind Brody moves to reveal a studio backlot, leaving viewers wondering whether the show was scripted or not.
But now, according to Entertainment Weekly, MTV bosses have decided to treat American fans to a different ending as part of their 'RetroMTVBrunch' on 9 August.
Throughout the day, the channel will air old episodes of The Hills, along with its predecessor Laguna Beach, before showing the special ending.
Unfortunately, there doesn't appear to be any plans for it to be aired in the UK, but no doubt we'll get to hear all about what happens!
In the meantime, let's keep our fingers crossed that MTV UK will decide to let us in on it too. Please!
