Kylie Jenner just turned eighteen and this gives her a leeway to be very open about her relationship with 25-year-old rapper Tyga. Kylie just made it very clear to everyone that they are dating after she posted a racy video of her and Tyga kissing.

Kylie took to Snapchat to share their intimate moment last Saturday while the two were at the Alexander Wang afterparty, according to People. The couple also attended the Fashion Runaway show at ier 94 in New York before heading to the party.

The video was as sensual as it could be. Jenner grabs Tyga's face towards her and "seductively bites his lip as he grins widely, showing off his grills," People noted.

The couple's relationship has been all over Snapchat. According to Hollywood Life, Tyga bragged about Kylie's "marshmallow booty" in a different video by the rapper as Kylie "nuzzled up to his neck."

Though there are others who do not approve of their relationship, the couple seemed to be enjoying their time.

A source told Hollywood Life that Kylie really feels Tyga is her soulmate.

"He gets her like no one else does. Even when they first met when Kylie was younger, Tyga always treated her like an equal. He always made her feel important, and still does. Tyga is Kylie's everything! A lover, best friend, and mentor. He's her rock," said the source.

It was also reported by Hollywood Life that the two are already engaged. The couple are just keeping everything under wraps for now but there is a Cartier ring that will reportedly prove this.

"Tyga and Kylie are engaged," the source told Hollywood Life. "He gave her that ring and asked her to marry him. They aren't ready to tell everyone so right now, they're keeping it a secret from most people."
