“She’s lying about everything,” Clint House claimed during Sunday night’s premiere of Casey Anthony: Her Friends Speak. The ex-roommate of the “most hated woman in America” opened up on Reelz about her demeanor following Caylee‘s disappearance.

“The thing that has driven me crazy was the fact that she was completely the same person during that time Caylee was missing,” he said. In fact, Clint claimed she even took part in a “hot body contest” during her daughter’s disappearance.

Just four days after Caylee was last seen on July 16, 2008, Casey was captured in various photos celebrating at Fusion nightclub at a party hosted by Clint. However, he insisted no one knew the toddler had vanished.

“At that time, none of us knew that Caylee was missing,” he explained. “We couldn’t be surprised. We weren’t surprised until after the fact, until police were talking about it, asking questions. Until the media got ahold of it and things exploded. We were shocked and surprised that she could be out here doing what she had been doing that night, and meanwhile, her child is missing. It came as a big shock once we found out about it. But we just didn’t know.”

Clint also claimed the last time he saw Casey before the trial was in downtown Orlando on July 3.

“She just didn’t seem like there was anything wrong,” he said. “She was like, ‘Hey, how’s it going? Good to see you.’ Then we went our separate ways. That’s the hardest part about this whole story, is that she was just completely so normal during the time Caylee was supposedly missing.”

Casey’s childhood friend, Jonathan Daly, agreed, adding, “Everything was normal. Everything was the way it was before Caylee was missing… while she was missing.”

Casey was ultimately acquitted after being found not guilty of first-degree murder, aggravated manslaughter, and aggravated child abuse in 2011 — but how was she able to get off?

One juror, Jennifer Ford, told ABC News at the time, “I did not say she was innocent. I just said there was not enough evidence. If you cannot prove what the crime was, you cannot determine what the punishment should be.”
