A source told HollywoodLife.com: "Kendall and Harry have been talking and texting again. They are just friends right now but the conversations can be flirty as Harry can't help himself."
The insider added, "He's very charming. He makes Kendall laugh which she loves. They have even been planning on going out with their friends when Harry is in LA and available."
But isn't Harry always in LA when he's not touring?
The source also claimed that "Kendall's relationship with Harry really bothers Justin [Bieber]," explaining that Justin gives her a hard time when Harry calls. The insider believes that "Justin definitely sees Harry as a threat - not just with Kendall, but professionally, too. Justin want Harry to keep his distance."
A love triangle really seems unlikely, but we'll if anything develops between Harry and Kendall again.
