'The Hills' Stars Heidi Montag and Spencer Pratt on Surgery Regrets and the Need to Be Famous Again

"The Hills" made its young cast famous in the 2000s, and at least two of them are eager to be famous again as the show returns to MTV after nearly a decade away. Hey, it worked for the "Jersey Shore" cast.

"The Hills: New Beginnings" marks a return to one of the signature reality shows of the genre's breakout era, and the first to openly admit that much of it is at least somewhat scripted or pre-planned. Nevertheless, the show made major stars out of Heidi Montag, Spencer Pratt, Kristin Cavallari, Lauren Conrad, Whitney Port, Audrina Patridge and many others.

And while several of the OG cast will not be back for "New Beginnings," you can bet Speidi was on board from the beginning, even if the show promises to bring up "a volcano" of old drama.

"Oh my god, these are people that I have been avoiding these conversations [with] for 10 years," Spencer told ET.

Nevertheless, he's looking forward to returning to the small-screen and he's not shy about admitting why, saying he's "definitely more motivated." He went on to add, "I thought I was done trying to be famous and I was accepting living in Santa Barbara and just eating tacos. And then we had a kid, and I'm like, 'I must be rich, my son must be on a jet. Like, I need to be famous again!'"

Hopefully, should that happen, the fame will sit better for the reality couple now that they're older and the parents of a two-year-old than it did the first time when Heidi decided it would be a good idea to undergo 10 cosmetic procedures in one day and nearly die in the process.

You know. Like you do.

Heidi still stands by her decision to be open about her plans to go under the knife, but she's not as steadfast behind every decision she made.

Saying that she's "in a different place" in her life now, Heidi told ET, "I do look back and go, 'Wow, that's a big thing I did and I should have thought about it longer. That was an intense decision to make at such a young age.' I just feel like I had a lot going on and I didn't think about it enough."

Of course, Heidi was in hear early 20s when she made that decision, and not thinking things all the way through is all too common at this impulsive age. Now, at 32 years old, the reality TV star, wife and mother has a richer perspective on what's important.

One thing Spencer said he wished they had done differently when they were being portrayed as the villains on "The Hills" was to maybe handle interviews outside of the show better, rather than lean into their television persona. He wishes they'd have admitted "it's fun and TV and like, so amped up."

That might have helped the public's perception of them in the real world, which lined up pretty well with their reception on-camera from their so-called friends.

The real question for "Hills" fans will be if and how Speidi has evolved and grown since "The Hills" wrapped production in 2010 after six seasons and more than 100 episodes. They'll also be eager to see how the villains get along with the rest of the returning cast.

They'll have to make do without Conrad, Cavallari and Lo Bosworth, who will not be returning, but they can look forward to Patridge, Port, Stephanie Pratt, Jason Wahler, Justin Bobby Brescia and Frankie Delgado, for sure.

They can also expect some other new and familiar faces, including cast-member spouses, Pamela Anderson and Tommy Lee's son Brandon Thomas Lee and "The O.C." star Mischa Barton. Wait, is this scripted again? Well, probably at least a little bit.

We'll all find out just how real it is -- or we can start speculating -- when "The Hills: New Beginnings" kicks off its new run on June 24.
