Kendra Wilkinson is very protective of her ex-boyfriends.
The 27-year-old Playboy model broke things off with the magazine's founder, Hugh Hefner, in 2008, but that doesn't mean she's okay with it when someone else dumps him.
While appearing on the "Big J" radio show in Montana on Tuesday morning, Wilkinson slammed Hefner's new wife, Crystal Harris, for dumping the octogenarian just five days before they were scheduled to get married in 2011.
"I got pissed off when she hurt him and he can't go around thinking that people will automatically love her, especially after that," the former "Girls Next Door" star said. "That pissed everybody off, that she would just leave him and dump him, use him and abuse him."
Wilkinson added, "Of course, someone like me, I wanted to kill her. So now he's trying to get people to love her again."
Wilkinson revealed that when she spoke with Hefner at the Playboy Mansion last week he told her he had no regrets about walking down the aisle for the third time:
"It was just me and him and I looked him in his eyes and said, 'Hef, are you happy?' And he's like, 'Oh, am I Kendra! I've never been this happy, and I want you to tell everybody that.'"
