Los Angeles - Kylie Jenner has been "courting" PartyNextDoor for two months.
The Keeping Up With The Kardashians star split from boyfriend Tyga earlier this month but had been friendly with the 22-year-old rapper - also known as Jahron Anthony Brathwaite - for over eight weeks.
A source told Us Weekly magazine: "He actually began courting Kylie two months ago. They were friends but now they're definitely together. He's a good guy and very chill. Kylie was really over being the joke of this whole Blac Chyna-Tyga situation."
Meanwhile, it was previously revealed that the 18-year-old television personality's romance with PartyNextDoor was quite sudden.

A source said at the time: "Their relationship started quite suddenly but it just feels right. They are mad for each other. She doesn't know why she wasted time with Tyga.
"Kylie's family found the eight-year age gap with Tyga a bit weird, especially as they got together before she turned 18 last year. PartyNextDoor is much better as he's only four years older than her."
Meanwhile, Kylie and Tyga are said to have split because she could no longer trust him.
A source revealed: "He was lying repeatedly to her face and she just couldn't take it anymore. She couldn't trust a word he said. They were fighting a ton over stupid, petty things over the last few months, and she was over it."
