The Hills' Star Spencer Pratt is known for voicing his opinion when he is upset.
On the show, Spencer was embroiled in lots of drama and known for his snappy comebacks and holding grudges.
And recently the reality TV star has been hitting out at his co-stars for their "ill-treatment" of him and wife Heidi Montag.
He has been bad-mouthing his co-stars on social media when fans of the show quizzed him about the rift.
In response to a tweet that asked if any of his castmates have apologised to him and Heidi for “how they treated” them, he said: "No, they’re the worst people ever,” Page Six reports.
The fan then claimed that the cast is jealous of the couple.
"They ALL knew you two were going to be the stars (you know, because you have personalities and [your son] Gunner) plus you and [Heidi] have gained a following over the years so, in my opinion, they wanted to push you guys out."
In response, Spencer said: “Big facts”.
Fans of the show reckon Spencer is upset after being held accountable for his comments about Jason Wahler’s sobriety.
There was an explosive row after Brody revealed to Jason and Justin Bobby that Spencer accused Jason of not being sober.
Ashley and Jason attempted to speak to the Pratts about his behaviour in episode 8 during the group’s murder mystery game.
Spencer was immediately dismissive, saying: “I’m not talking to these two.
He tells Ashley: “I don’t want to talk,” plus “and I don’t need to have a reason”, and then adds fuel to the fire by repeating what he said about Jason.
He added: “My exact quote was, ‘I don’t know about Jason’s sobriety. I don’t know if he’s sober. He’s sober, then he’s not sober.
A fierce row then takes place between The Wahlers and the Pratts, which culminates in Heidi and Spencer storming out of the room.
Spencer and Heidi – or ‘Speidi’ as they are commonly known – first found fame on The Hills.
They married in 2008, although they’re known for their rocky relationship.
Spencer is also known for his fiery temper.
In January 2013 the pair went into the Celebrity Big Brother house as one contestant.
