Wait, what?!
Kim Kardashian once filmed scenes for season three of The Hills! Yes you read that right. But if you're wondering why you don't remember her on any episodes, it's because her scenes didn't end up making it on the show.
On Tuesday's The Hills: That Was Then, This Is Now special on MTV, the network showed a deleted scene in which Kim attended Heidi Montag and Spencer Pratt's housewarming party. And while Kim and Lauren Conrad didn't cross paths (Lauren didn't attend the party), Kim did have a conversation with Heidi about her and Spencer's fish tank and the MTV Video Music Awards.
But that wasn't the only revelation made on Tuesday's special! Take a look at the E! News video above to see more jaw-dropping moments from The Hills: That Was Then, This Is Now!
