You know? It’s really gotta suck being Tyga right about now.

While the “Rack City” rapper was somewhere being irrelevant this past weekend, his ex, Kylie Jenner was all boo’d up with PARTYNEXTDOOR at Drake’s (now infamous) Memorial Day party.

TMZ has footage of the two on the dance floor together, and they look very couple-like.

A source at the party told People that Kylie and PND “were all over each other, kissing and making out.”

Kylie and PND have been spending quite a bit of time together since her break-up with Tyga. The youngest of the Kardashian clan recently shared videos of her and PND hanging out on Snapchat. In one of the videos, PND plays the piano while singing “Kylie, oh Kylie.”

The other clip shows Kylie telling PND that he is too private about their relationship after he deleted a video of them bowling.

“You not only hide me, You delete me,” she says. PND responds, “No I don’t man, I’m protecting you.”

Tyga and Kylie split last month after dating for two years, so Kylie is free to date and get screwed by whoever she pleases. Hopefully Tyga will do the same.
