Justin Bieber is dating Kourtney Kardashian, who is 15 years older.

Bieber, the young pop star, has made his love life an open book. Almost everybody is aware of his hook ups with famous female celebrities and his on-and-off relationship with Selena Gomez. 

Many believed that the hook-ups are just very big rumors especially that Kardashian had just finished off her 10-year relationship with Scott Disick. Their relationship fell apart because of Disick's love for two things that Kardashian does not like, partying and girls.  Beiber's life has a similarity with Disick's, but the young pop star has no other responsibility aside from himself.   

Many see that this period is critical in Kardashian's life and that she should really think things twice.  However, Bieber is showing that he has changed for the better and is more mature when it comes to relationships.

The on-going relationship between the two has been confirmed by a source who stated that, "Justin has a real genuine interest in Kourtney. She's seasoned and mature and her energy compliments Justin's. Not to mention, he loves older women. He loves how most of them are dominant and know exactly what they want. Kourt doesn't play childish games like women his age, and he loves that. His respect level for Kourt is through the roof because of it," Hollywood Life exclusively reported.

It all started in "The Nice Guy" back in October and they seem to be inseparable ever since, US Magazine reported.  The mother of three kept on denying any wrong doing to her family.

When the hook up reached the younger and more famous of the Kardashian sisters, she got unhappy. Kim does not totally agree with the dating idea, saying it is like Kourtney having a fourth child. Kanye West's wife said that the age and lifestyle difference is a big factor on the said relationship.
