The new Us Weekly (on newsstands now) reports that Spencer Pratt has huge rage issues.
On Tuesday's episode of The Hills, he showed just how scary he can get.
He had a violent outburst after Heidi's sister Holly confronted him about a crude remark he made about their mother being "just a vagina."
"I thought by this time you would have enough respect for me to be able to refrain from speaking about my mom like that in front of me," she told him.
With his anger building, Spencer then howled loudly before telling Holly he didn't think he said anything wrong.
As Heidi repeatedly urged him to take deep breaths, Spencer lost it completely. "Your mom IS just the vagina that made Heidi come onto earth!" he shouted. "Your mom is not Jesus, or God, or the Creator!"
As the bickering continued, he stormed off, slamming the door.
Holly then began crying as she confided in Heidi. She said she feels she'll never have a relationship with her sister again because of Spencer. She doesn't even have Heidi's number anymore.
Unable to control herself, she yells: "He scares me!"
