Kourtney Kardashian 'Just Wants to Have Fun' with Justin Bieber

Kourtney Kardashian plays with her hair while walking to her car on Wednesday (December 16) in Reseda, Calif.

The 36-year-old reality star showed off her taut tummy in a black crop top and pink sweats. She was picking up daughter Penelope and niece North (both not pictured) from dance class.

According to People, Kourtney and Justin Bieber are just enjoying each other’s company for now. The twosome have been spotted hanging out over the past couple of weeks but sources claim it’s nothing too serious.

“It’s just one of those things where it makes Kourtney feel good about herself. It’s not serious at all,” said a source. “She just wants to have fun.”
