What's Going On Between Kendall Jenner And Anwar Hadid?

Kendall Jenner has been romantically linked to several people in 2018, but the one that seems to have caused the most speculation so far is Anwar Hadid. And, yes, he just so happens to be Gigi and Bella Hadid's younger brother.

The two were reportedly seen kissing at an afterparty for the CFDA Awards on Monday. (See the photo here.) Days later, they were seen together again on a more casual outing at Gigi's NYC pad.

Here's everything you need to know about Kendall and Anwar's rumored romance.

Anwar is Gigi and Bella's 18-year-old brother—and he's also a model.

While the famous models have several half-siblings, Anwar is their only full sibling, per Cosmopolitan. They're extremely close, and Gigi and Bella regularly post Insta photos of Anwar, and vice versa:

While Gigi is currently 23, and Bella is 21, Anwar is 18-years-old. For reference, Kendall is currently 22.

He's appeared on the cover of several publications and was the face of Hugo Boss in 2017. Like his older sisters, he's walked the runways at fashion week for designers including Tommy Hilfiger, Ralph Lauren, Philipp Plein, and Zadig & Voltaire. Clearly, Bella and Gigi's little brother has a lot in common with Kendall.

Kendall is reportedly casually dating a basketball player.

The model had recently been linked to basketball player Ben Simmons, a point guard on the Philadelphia 76ers, however their romance appears to be casual. She was just spotted on a bike ride with him around The Grove in West Hollywood last weekend. At the time, an "insider" told Page Six that Jenner and Simmons had been dating "for a few weeks."

But she's not interested in a serious relationship right now.

“Kendall is having fun. She doesn’t want a serious relationship and is just enjoying being single,” a source told People after the Anwar Hadid and Ben Simmons news. “She feels that whenever she has been serious about guys in the past, it’s kind of a mess and doesn’t work out. She invested time in the relationship with Blake Griffin. She isn’t planning on doing the same right now.”

Anwar was previously dating actress and model Nicola Peltz.

Meanwhile, Anwar had been seeing Nicola Peltz, 23. Since TMZ broke the news about Kendall making out with Anwar, Peltz has unfollowed the entire Hadid family on Instagram, suggesting that she's no longer seeing him. She'd also deleted all photo evidence with Anwar on her Instagram page, though he still has photos with her on his account. The Daily Mail reports that Peltz and Anwar broke up in May 2018.

Kendall and Anwar's make out session wasn't that serious.

TMZ reported on Wednesday that their "sources say the two aren't dating or anything serious... they were just having some fun while out with friends. We're told there's no bad blood with Kendall, Bella and Gigi."

Per TMZ, Kendall and Anwar were apparently "kissing, cuddling and drinking" for around two hours at the party, before leaving separately.

This isn't the first time Anwar and Kendall have been photographed together.

Back in 2016, Kendall shared a suggestive photo with Bella and Gigi's younger brother. Pretending to kiss him on the cheek, Kendall simply wrote the caption, "dibs?"

They were also spotted shopping in Los Angeles with Gigi back in July 31, 2015:

They were seen hanging out again days later.

On Wednesday night, Anwar and Kendall were seen heading into Gigi Hadid's NYC apartment together, though they tried to keep the appearance low key. Anwar hid under a hoodie and Kendall covered her face from cameras.
