Well, that didn't take long.
Kylie Jenner is now rumored to be getting friendly with up-and-coming rapper PartyNextDoor, after news broke last Thursday that she and her on-again, off-again boyfriend, Tyga, have split.
The 18-year-old reality star and the 22-year-old Canadian rapper were videotaped together on Wednesday night at the TCL Chinese Theatre in Los Angeles, where they went to Russell Simmons' All Def Comedy Live, TMZ reports. Kylie dressed casual for the meet-up, rocking a bomber jacket and high-top sneakers, and accessorizing with a backpack.

PartyNextDoor also gave a shout-out to Kylie on Instagram last week, posting a picture of the two sporting glitzy watches together.
"Diamond battles with @kyliejenner," he captioned the pic.
... And it didn't take long for Tyga to clap back.
"Diamond battles," he captioned a similar pic of himself a day later, wearing significantly more diamonds than both PartyNextDoor and his ex-girlfriend.
So, just who is Kylie's rumored new beau? The rapper, whose real name is Jahron Anthony Brathwaite, is signed to fellow Canadian Drake's OVO Sound record label. He's collaborated multiple times with the "Hotline Bling" rapper, as well as with rappers Big Sean and Rihanna's rumored fling, Travis Scott.
PartyNextDoor made his own headlines in March, when he was involved in a reported love triangle involving his ex, singer Kehlani, and NBA star Kyrie Irving. Kehlani -- who is featured on Zayn Malik's album, Mind of Mine -- was accused on social media of cheating on Irving with PartyNextDoor (whom she dated prior to Irving) after the rapper posted a photo to Instagram of Kehlani in bed with him. Following the onslaught of negative tweets and memes, the 20-year-old R&B singer Instagrammed -- and later deleted -- a photograph of her tattooed arm attached to a hospital IV, after an alleged suicide attempt.
Irving later addressed PartyNextDoor's since-deleted Instagram post that led to the firestorm, tweeting, "I do not justify the picture or what dude did to try and spark all of this nonsense that could have been avoided, but me and Kehlani were not dating when the picture came out."

Meanwhile, Tyga broke his silence on his split from Kylie last Friday.
"We're both just focused on our individual lives," he said when approached by a TMZ photographer at Los Angeles International Airport. "And sometimes things don't work out."
"But, you know, I love her," he added.
