While Pratt didn’t have a problem slamming a certain cast member for their past actions, it seems as though any chance of these two ever making amends is now out the window.

Pratt doesn’t think her brother is responsible for the rumor

When it comes to The Hills, there is never a shortage of drama and Stephanie Pratt just proved that to be true.

On July 23, the reality star took to Instagram to call out her fellow castmate and sister-in-law, Heidi Montag, for being the one who started the sex tape rumors that involved Lauren “LC” Conrad.

Back in 2008, rumors began circulating that Conrad allegedly made a sex tape with her then-boyfriend Jason Wahler. 

Though Conrad completely denied those claims, it was to be believed that her best friend, Heidi Montag, was in on spreading the rumor, which ended with her screaming at Montag — in one of the Hills‘ most intense moments — “You know what you did!” 

Even though Heidi Montag received heat from Lauren Conrad, the reality star’s husband, Spencer Pratt, eventually admitted to leaking the story.

While we aren’t sure what caused Stephanie Pratt to bring up the sex tape, the reality star didn’t hold back in her Instagram post that claimed Montag was the one who spread those rumors about Lauren Conrad.

After sharing how grateful she is to be back in London and way from “evil siblings,” Stephanie Pratt calls out her sister-in-law for lies she’s made up about Conrad.

“Heidi- I have no words for how evil you truly are- you had no choice to admit all of the lies you’ve been spewing about me was for a magazine cover 🙈 and for real WE ALL KNOW WHAT YOU DID 10 years ago,” Pratt wrote. “You awful human being- and to your BEST FRIEND? You are truly a hideous person. No wonder you don’t have 1 friend (your nanny doesn’t count- you pay her).”

Heidi Montag has denied spreading those rumors

While Stephanie Pratt is certain Heidi Montag is guilty of spreading lies about Lauren Conrad, the reality has denied ever doing so in the past.

During The Hills: New Beginnings premiere last month in Los Angeles, Montag admitted that she had no part in spreading that rumor about her former best friend.

“We are at the scene of that! And I know I never did anything, but that’s fine!” she said.

As for Montag’s relationship with Stephanie Pratt, the reality star recently claimed that she and Spencer Pratt no longer have issues with her.

“We have nothing but love,” she said, but Stephanie Pratt claimed that that is far from the truth.

“We’re not on good terms. We are not on speaking terms. I do not consider them my family,” Pratt revealed during an episode of her iHeartRadio Pratt Cast podcast.

While Stephanie Pratt will most likely never make amends with her brother and his wife, we’re pretty sure this just made forgiving each other even more unlikely.
