The 29-year-old reality star recently did a beach photo shoot with the teen sensation, 16, for ELLE magazine but said they are nothing more than friends.
Speaking to Extra, Kim said: "I think it shows obviously he has a huge following of young girls. We would not seriously date. I could literally be his mum. To all the Bieb-lievers out there, we're just friends."
This is not the first time Kardashian has been forced to confirm she isn't dating the singer as his fans got upset back in May when they posed in a picture on Twitter.
