 " All Good Things ... " was produced by Adam DiVello , Michael Friedman , Liz Gateley , Josh Lansky , Kristofer Lindquist , and Sara Mast . The sixth season was first announced in December 2009 , and was confirmed to be the final season in March 2010 . Upon the announcement , speculation arose that original focal point Lauren Conrad would return for the finale . Her former boss Lisa Love suggested that a scene could be filmed of the pair reuniting in Paris , while series creator DiVello wished to see Conrad getting married , presumably to her then @-@ boyfriend Kyle Howard . Cavallari stated that it would be " amazing " to see Conrad return , adding that her appearance would provide the program with " closure " . Ultimately , Conrad did not appear in the final episode , but was featured in the live aftershow , The Hills Live : A Hollywood Ending .
