While The Hills is probably best known for the tension that played out between Lauren Conrad and Spencer Pratt, Spencer wasn't the only co-star Lauren had trouble getting on with.

As regular Hills viewers will know, another seed of resentment bubbled beneath the surface for years, and it involved Lauren and Audrina's on again/ off again boyfriend Justin Bobby.

While they never had too much face-to-face animosity, the reality show devoted numerous scenes to documenting the pair's mutual distrust of each other.

Whether it was Lauren warning her friend off the biker boy – "Homeboy wore combat boots to the beach" – or Justin urging Audrina to reconsider her friendship with LA's favourite headband-wearer, it's safe there was no love lost between JB and LC.

And while it doesn't seem like Lauren has given Justin a second thought since leaving the show, Justin has PLENTY to say about her Laguna Beach alumni.

With MTV celebrating the show's 10th anniversary, Audrina's former flame decided to speak out and share his opinion of Lauren.

"She wasn't the most down-to-earth. You get a young girl like that, who has been on TV since she was 18, and her whole life's exposed – how do you get an actual normal person at that point?" he asked while speaking to Broadly.

"You don't get someone who's down-to-earth and someone who's loving and caring," he raged."You get someone who's f*cking twisted."

In comparison to his opinion of Heidi's former BFF, Justin is a major Speidi fan, continuing: "I liked that their love stayed true.  I mean they had so much ridicule for doing what they're doing, and they're still together."

"They're still saying, 'Fuck you.' That to me is like, 'You guys won all the way around.'" he added.

This is all the evidence you need that you should NEVER mock a man's decision to change his name.

Nope Justin, clearly not.
