Kim is currently dating rapper Kanye West and Jenner said that the 31-year-old is content with her life, reported E! online.
"I've never seen Kim this happy. She's calm, she's happy, she's content in her life right now. I think she's working hard, she loves what she's doing, she's passionate about her projects, and she's loving life right now," Jenner said.
Jenner, who has been skeptical about Kim's relationship with the singer, doesn't rule out that her daughter could get married to West.
"I think there's always a chance when you're dating someone that they could be the one," she added.
