Kourtney Kardashian isn't letting her split from longtime boyfriend Scott Disick stop her from enjoying a fun night out on the town. The newly single mother of three was spotted partying with pop star Justin Bieber Friday night, sparking rumors that the pair may be a new item.

TMZ posted a video of the "Keeping Up with the Kardashians" star and Bieber leaving a nightclub called The Nice Guy in Los Angeles before hopping into a waiting black SUV together. As Kardashian and Bieber made their way to the car, photographers bombarded them with questions about whether they were dating. The site reported that the 21-year-old "Boyfriend" singer and the 36-year-old reality-television star arrived at the venue separately, but apparently linked up once inside. Watch the video here.

It's unclear the outing represents the beginning of a new romance, but it shouldn't come as a surprise that the pair is hanging out because the singer is close friends with almost the entire Kardashian-Jenner family.

Bieber has been spotted with Kendall Jenner and her sister Kylie Jenner on several different occasions, and the "Confident" singer has even hung out with Kourtney Kardashian's young son Mason Disick.

In March, Kardashian and her mom Kris Jenner shared the same photograph of Bieber playing with the 5-year-old boy in a pool. “Mason & @JustinBieber family pool day!! #bestbabysitterintheworld," Kris Jenner captioned the picture.

Kardashian ended her almost 10-year-old relationship with Disick in July after photos surfaced of him getting close to Los Angeles-based stylist Chloe Bartoli.

The reality-TV star -- who shares kids Mason, Penelope and Reign with Scott Disick -- reached out to her fans this week after a preview of Sunday's "Keeping Up with the Kardashians" showed her crying over the split. "Reading your tweets and I need you guys to know how truly touched I am by your love," Kardashian tweeted. "I love you guys. You help me more than you know."
