'The Hills' is alive... but not for much longer.

The cultural phenomenon that sparked a generation of non-reality reality shows is launching its sixth and final season starting on April 27, with a spectacular summer series finale planned. Many are rejoicing the demise of the show, practically chomping at the bit to send Heidi Montag and Spencer Pratt into the sunset. Others aren't so happy... though we're not sure who you are.

Some of the final episodes include Montag's plastic surgery being revealed to her mom, the cast dealing with substance abuse, and Audrina Patridge dating Ashlee Simpson's reality TV ex, Ryan Cabrera. There has been some teasing in regards to the return of Lauren Conrad, but MTV makes no promises.

We sat down to talk candidly with Dan & Jessi from MTV Canada's 'The After Show' about the end of 'The Hills,' and what the remaining fans have to look forward to in the next few months.

'The Hills' and 'The City' are gearing up for new seasons, and there's plenty of romances, break-ups, partying, new betrayals and new alliances ahead.

Both shows premiere April 27 on MTV, and the love lives and careers of Heidi, Spencer, Brody, Audrina, Justin, Whitney, Roxy, Olivia and Erin will continue to dominate the new seasons.

More previews and videos after the jump.

All good things must come to an end, even 'The Hills.'

Ladies and gentlemen, what we have here is the trailer for the final season of the MTV reality hit.

We've watched them love, live and grow -- and in Heidi Montag's case get loads of plastic surgery. This trailer opens with footage from simple times, times before plastic surgery and sex tape rumors. That alone was enough to make us nostalgic for the days of Whitney and Lauren sitting around the offices of Teen Vogue, but then -- BAM! -- new footage that got us excited (don't judge).

Check out the video after the jump.
