Heidi Montag and Spencer Pratt tied the knot in 2009 and are still going strong.

The pair met in 2006 at a nightclub while Montag was filming The Hills, and it was love at first sight for the reality star. "I pretty much told everyone I was going to marry him and that I loved him. [Everyone] thought I was crazy," she told Vice in 2016.

Pratt was then cast on the hit MTV series and their relationship played out on the screen for six seasons.

The couple has had their fair share of struggles over the years, including a brief separation in 2010, but they have since welcomed a son and have another baby on the way.

"When we started, it felt like everyone was trying to break us up, or they thought we were together to be famous," Pratt told PEOPLE in an exclusive interview in 2019. "But here we are, 10 years later. The [best] thing we ever did is be together."

From their early beginnings on The Hills to walking down the aisle (twice) and having kids together, here's everything to know about Heidi Montag and Spencer Pratt's relationship. 

Early 2006: Heidi Montag and Spencer Pratt meet

Montag and Pratt first locked eyes at the now-closed L.A. club Privilege, which was located on the Sunset Strip in West Hollywood. Pratt had been visiting the club with his friend Brody Jenner, looking for a way to get a role on The Hills.

"I was like cartoon goo-goo eyes, heart falling out of my head," Montag recalled of their first meeting during an interview with Vice.

Pratt had also fallen for Montag and he began to pursue her. Soon after, he joined Montag on The Hills and the two began crafting up dramatic plot lines to turn the attention away from protagonist Lauren Conrad and onto "Speidi," their self-dubbed couple name.

"I was treating the show like a producer because I literally just made a show on Fox," Pratt explained to Vice. "I didn't know how to be on-camera talent."

"I am surprised and not surprised at the same time," their Hills costar Audrina Patridge told PEOPLE. "They obviously adore each other and are very committed to one another. Heidi and Spencer seem like the types who would want a lavish wedding full of friends and family. I do think it's very romantic that they eloped."
