Last month, the youngest member of the "Keeping up with the Kardashians" clan turned 18, and since that moment, her relationship with 25 year-old rapper Tyga has become official, even offering some heavy Kylie Jenner and Tyga PDA during their most recent appearance together.

During the New York Fashion Week 2015, Kylie Jenner and Tyga's PDA has been seen all over the place in the event, with the youngest daughter of Kris and Caitlyn Jenner showing off how in love she and her man are.

According to Hollywood Life, Kylie Jenner and Tyga's PDA was a long time coming, as the couple has been together for a while, although they were keeping their romance in the lowest possible profile because of their age difference, as Kim Kardashian's little sister was underage at the time the two began going out, prompting accusations of statutory rape.

As InTouch Weekly reports, the NYFW has served for Kylie Jenner and Tyga's PDA to finally come forward, as the 18 year-old, famously active in Snapchat, has been posting some serious love towards her man on the social network, from kissing videos to hanging out together in what seems to be a hotel room as she says he's "so cute."

"Kylie and Tyga have been having a really fun Fashion Week together," an insider told E! Online recently, as more and more reports of Kylie Jenner and Tyga's PDA in the past few days. "It just feels good for both of them to be out in the open and not hide and pretend they aren't dating. They feel way more at ease."

It seems like they're also quite comfortable with the star's famous family, as they're all hanging out together during the shows, with supermodel sister Kendall Jenner currently working at the major fashion event.
