Justin Bieber And Kourtney Kardashian Reportedly ‘Casually Hooking Up,’ Having ‘Fun’

Justin Bieber and Kourtney Kardashian are a thing. Yes, you read that right.

Justin Bieber, 21, and Kourtney Kardashian, 36, have reportedly been “casually hooking up” for a while.

The unexpected May to December relationship isn’t serious, but occurs occasionally, a source confirmed to Gossip cop. “It’s just fun”, the outlet was told by an insider.

News of Kourtney and Justin’s particularly close relationship comes after the pair were spotted enjoying an evening out at Los Angeles hotspot The Nice Guy in West Hollywood, followed by the karaoke lounge Blind Dragon on Friday, December 11.

The mother-of-three, who wore a structured white bodysuit tucked into high-waisted slim leg trousers, was snapped arriving at The Nice Guy with Corey Gamble, who is the boyfriend of Kourtney’s mother, Kris Jenner, and the Biebs’ day-to-day go-to guy.

Meanwhile, Justin rocked up to the eatery/bar in a more casual look. The “Sorry” singer wore an orange T-shirt, a black hoodie, black trousers, and a camouflage baseball cap.

He later shared video clips on Instagram of himself jamming at the popular restaurant.

Paparazzi snapped Justin playing about Corey in front of the singer’s brand new electric blue Ferrari.

Entertainment Tonight reports the Biebs was apparently parked illegally and ticketed by police earlier that night.

Of Kourtney and Justin’s time at the karaoke lounge, an eyeitness tells Us Weekly, “They were hanging out in a group of about seven, and then [the Biebs] went into one of the private karaoke rooms and she left about an hour and a half before he did.”

However, that wasn’t the end of the evening. From there, TMZ revealed Kardashian went to the Beverly Hills Montage hotel where Bieber has been staying for months. The brunette was later photographed leaving the hotel at 4 a.m.

This isn’t the first time Kourtney and Justin have hung out. Back in March, she and her younger sister Kendall attended the Biebs’ Comedy Central Roast in L.A. In October, Kourtney and the Canadian singer dined at The Nice Guy before going on to the Universal Studios theme park.

The singer later shared an Instagram selfie of the pair wearing 3-D glasses for Universal’s “Halloween Horror Nights.” They reportedly spent time together later that night.

More recently, Kourtney was a guest at Justin’s post-AMAs party at The Nice Guy on November 22, where he celebrated the release of his chart topping comeback album Purpose.

As per reports, Kourtney, who is the oldest of the Kardashian sisters, isn’t getting back with her ex Scott Disick, with whom she has three children, Mason, five, Penelope, three, and Reign, who will be one in two days time. Although the two have been seen together in recent weeks, TMZ alleges Disick and Kardashian are civil for the sake of their kids.

Kourtney and Disick, 32, split up in July after Scott was photographed in suggestive pictures with his ex-girlfriend Chloe Bartoli in Monte Carlo. Since then, Disick has been in rehab, which he left last month.

Justin is a longtime friend of the Kardashian-Jenner clan. He was a babysitter for Kourtney’s oldest child, Mason, earlier this year, he was featured a in Vogue photo shoot with close pal Kendall Jenner, and (as mentioned) his tour manager Gamble is dating momager Kris Jenner.

Revelations of Kourtney and Justin “hooking up” come after The Sun, a British tabloid, alleged Bieber and friends partied with four girls at a London hotel after the singer headlined Capital FM’s Jingle Bell Ball in London last Sunday, December 6.

The paper later revealed the police were called to the hotel at 6:15 a.m. and cited a vague scenario about one girl allegedly having a “meltdown.” Police later confirmed no offenses were committed and a rep for Bieber later told Hollywood Life that the story was “totally false.”

The Sun followed up that claim on December 11, publishing a story in which a British model alleges she enjoyed a threesome with the pop star at his London hotel after his concert.

Model Laura Carter, 30, alleges she was picked out from the dance floor at Tape nightclub and taken in a chauffeured car to an after-party at the plush Rosewood Hotel — where the singer was then staying — along with around ten other women. Carter’s claims, which have yet to be denied or verified, can be read here.

As for Kourtney and Justin’s newly-revealed intimate relationship, since both parties are single and fancy free, how they choose to spend their time is their own business.

While the superstar recently shared throwback pics of his former girlfriend, Selena Gomez, on Instagram, it seems he has moved on. Was that the reason for the Latina starlet’s recent Instagram shade?
