Kylie Jenner and PartNextDoor's romance is rumoured to be getting serious. Although The Keeping Up With The Kardashians star hasn't publicly announced her relationship with the rapper, born as Jahron Anthony Brathwaite, the pair are reportedly moving fast with their romance.

According to a report in US Weekly, Jenner's relationship with her new rumoured boyfriend has succeeded in becoming the "real thing."

"They're talking and texting nonstop," a source told the magazine confirming that "he's as into her as she's into him."

Jenner, 18, was first spotted with the 22-year-old rapper during a comedy show in Hollywood, and the duo later sparked romance rumours when they were seen cosying up to each other at Drake's Memorial Day party in California.

An insider told the magazine that, "They were introduced by Drake. And they were all over each other at his party, even though Kylie initially thought that this would be a rebound."

The Kylie Lip Kit owner was dating 26-year-old Tyga earlier, before she ended her relationship with the rapper in early May amid sex-tape controversies. While reports suggest that the teenager has moved on from the Rack City singer, it seems Jenner still stays in touch.

"They still text and share a group of friends," an insider claimed. "But there's not a relationship-y vibe between them anymore."

If rumours are to be believed, the youngest Kardashian-Jenner sibling finally seems to be ready to embrace a fresh relationship with the Come And See Me hitmaker. "She doesn't care about Tyga like she used to. As far as Kylie is concerned, Tyga can go do this thing," another source added.

However, Kardashian matriarch Kris Jenner seems to be worried that her daughter would be "hurt again." A report in Hollywood Life claims, "She's happy that Kylie's enjoying herself, but she's been encouraging her to not jump into a serious relationship with anyone."
