Kardashian then admitted she was getting death threats from Bieber's devoted fans. "I think they were 10-year-olds that got carried away, so he asked all his Bliebers to stop attacking me," she said.
Bieber was most recently spotted with Miley Cyrus, but said they were just "having fun."

Kardashian split from Reggie Bush again in March. The new issue of Us Weekly reports he'd like to win her back, but she has moved on.
