When we watched Heidi Montag and Spencer Pratt (fake) elope to Mexico inThe Hillsseason four, precisely no one believed it would last.

It was the first of a few manufactured engagements and weddings for the pair.

But then came the big church wedding in season five and well… nearly 14 years later, Speidi arestillgoing strong.

Spencer and Heidi appear in The Hills: New Beginnings. Post continues after audio.

However, it hasn’t exactly been smooth sailing.

When the couple first got together in 2007, it came at a huge cost to Heidi. She lost her best friend Lauren Conrad, who disapproved of their relationship (evenbeforeSpencer created a fake rumour about an LC sex tape) and her choices put a strain on her family relationships too.

After leavingThe Hills, Spencer, now 38, and Heidi, 35, worked Kris Jenner-hard to remain in the public eye.

Heidi released an album and three EPs (remember her single ' Body Language'? We're... sorry).

They also appeared on a number of other reality TV shows between 2009 and 2017, including:

In June 2010, Heidi filed for legal separation from her husband, citing irreconcilable differences and a month later filed for divorce.

They reconciled – officially – the following year, but as they would confirm in a 2011 interview with The Daily Beast, their entire break-up was fabricated.

"Did you ever break up?" they were asked.

"No," they both replied.

"Not for one minute," Spencer said.

"We’ve never even been apart," Heidi confirmed.

They said they faked their divorce in order to make some money – but it didn't exactly work.

"At that point, we were pulling our last cards,” Spencer toldThe Daily Beast. “We felt the hot-air balloon losing its gas. And at that stage, our income would be selling the photo that would go along with the divorce.”

At the time of the interview, they were broke and living rent-free with Spencer's parents.

After a couple of years laying low, Spencer and Heidi returned to screens on a series of reality TV shows and in 2017 announced they were expecting their first child.

This was around the same time Spencer decided to do something bold: take on Goop herself, Gwyneth Paltrow.

He began selling crystals, which eventually led to the creation of his crystal business Pratt Daddy. It didn't come out of nowhere though – Pratt was not shy about his decade-long love of crystals, which began duringThe Hills.

"My wife Heidi had some surgeries – nobody knows about them, they were a secret," he joked to Dazed Digital, when explaining how he got into crystals (Heidi famously had 10 plastic surgeries in one day).

"But the painkillers were not working. She was miserable, so I googled alternative healing methods and started reading about crystals. I went and bought [one that] would help the pain: Sugilite. I brought it home – I swear I bought the most expensive chunk of it, like $15,000, because my logic was that I needed the most powerful one. Heidi held it that night and slept for the first time in over a week with no pain. That morning, I went back to the crystal store. I was completely addicted."

One look at the couple's social media accounts shows their spirituality.

Spencer regularly spruiks his crystals on his Instagram (he loves to take close up videos of the necklaces, usually with a Taylor Swift song in the background).

Heidi uses her main Instagram account to post your usual #sponcon, plus supportive posts for Spencer's business and sweet family shots. She also runs a second account where she posts bible verses and images of her praying.

Heidi and Spencer welcomed their son Gunner on October 1, 2017, and in an interview with US Weekly following the birth, they explained how their spirituality made its way into the delivery room.

While Heidi breathed through contractions, Spencer hurried about with $27,000 worth of crystals.

"He’s running in [the delivery room], putting these huge crystals all over,” Heidi recalled. “It was mayhem!”

Heidi toldUS Weeklythat she and Spencer felt "blessed" to have such a "beautiful healthy baby boy".

"It was the hardest and most rewarding experience," she said.

Spencer described the day as "officially the most lit" of his life, because of course he did.

In 2019, the couple came full circle thanks toThe Hills: New Beginnings.

After more than 10 years of marriage, they told People their relationship was stronger than ever and they were excited to appear on the reboot of the show that originally brought them together.

"We have a much deeper understanding and love for each other now," Heidi said. "We've been through so much."

"We are pretty raw and open [on the show]. There are ups and downs. People will be able to relate, because when you become new parents and then you have jobs and friends and all these things, it does add new pressures."

Spencer acknowledged that for so long, nobody believed in their relationship except them.

"When we started, it felt like everyone was trying to break us up, or they thought we were together to be famous. But here we are, 10 years later. The [best] thing we ever did is be together."

While the show brought the couple back onto our screens,The Hills: New Beginningswas cancelled after two seasons.
