Recently, 21-year-old pop star Justin Bieber was spotted with 36-year-old "Keeping Up with the Kardashians" star Kourtney Kardashian. They were seen leaving a restaurant named The Nice Guy in West Hollywood.

Kourtney Kardashian, mother of three, was wearing a tank top and jeans while Bieber was in a gray basketball cap and hooded jacket and was trying to avoid the cameras as Kourtney boarded his SUV.

According to E! News, although they exited the restaurant together, they were dining separately with their own friends. Bieber arrived in the evening and gave a surprise performance to the diners on the piano.

Afterwards, the two were seen at the Universal Studios Hollywood at one of its Halloween Horror Nights. Bieber, who has been a longtime Kardashian family friend, also posted a picture on his Instagram of the two at a theme park wearing 3D glasses.

Bieber used to leave beside Kourtney's house and has a good relation with her kids and other family members including Kendall Jenner. His home in California was bought by Kortney's sister Chloe Kardashian in 2014 where Bieber's famous "Egg-Gate" debacle occurred.

Undoubtedly, he is very close to Kourtney and the way they both are spending a lot of time together. However, whether it is a causal bonding or something else, it is yet unclear.

Kourtney recently separated with her longtime boyfriend Scott Disick after being in a relationship with him for nine years. It was reported that she broke up with Scott because of his alcohol problems. There is a possibility that Kourtney is getting closed to Bieber to get out of the break up trauma.

Though it may look suspicious, neither Bieber nor Kourtney have confirmed of any sort of relationship with each other and only the time will tell how real the rumours are. For now, it seems Kourtney is really enjoying her time with Biebver and is moving on with her break up.
