When we thought Justin was more aware of the mystery girl I was talking through social networks ( it was mystery, here we reveal who it is ) or trying a second part with Selena Gomez , the guy stands out being with another famous than We did not expect.

His name, well known to all: Kourtney Kardashian . Sister Khloe and Kim Kardashian, on Saturday December 12, spent a day of the most intimate with the singer.

Apparently, the couple would have stayed for dinner, first, one of the trendiest restaurants in Los Angeles (The Nice Guy), after going to sing some songs at karaoke Blind Dragon.

But, maybe, it was yet to come. And, according to reports from PageSix, "after leaving the restaurant and go through the karaoke, the couple finally ended at the Mondrian hotel, where he was out Kourtney place at about 4 am ".

What happened inside the hotel? Is there something more than a beautiful friendship between Kourtney and Justin Bieber?

And that was a few days ago gave glances and Selena ...

For the moment nothing is known. Some say that this is a strategy to give Kourtney jealous ex, Scott Disick , after having broken up with her, had tried to return to her without luck.

This theory is supported by one of the photos you've shared the singer through social networks. In the picture we see someone who might be Kourtney, lying on a car with Justin doing something (apparently) might not be suitable for minors.

And, most strong that the photo in question is accompanied by a text ( Lord knows ) using the Lord as endearment with which he was known in the privacy Scott.
