PartyNextDoor's sweet serenade wooes Kylie

Is that sweet serenade, a chord for Kylie Jenner and rapper PartyNextDoor's blooming romance?

Just a few days after the 18-year-old reality star accused her rumored new 22-year-old beau of 'hiding' her and deleting her from his social media accounts, the two were recently seen spending some quality time, along with a piano, reports E! Online.

Jenner proudly showed off her private concert to her Snapchat followers recently, capturing her man tickling the ivories, singing "Kylie, oh Kylie."

Reportedly, the 'Come and See Me' artist recently took his new muse to Drake's Memorial Day house party, where the two were "all over each other," kissing and making out.
