Is Ariana talking to her ex, Nathan, again?

During a recent interview, Nathan Sykes was asked if he was still close to ex-GF Ariana Grande. His response? "Yeah, of course. When things don't work out, they don't work out. Long distances and stuff like that." The only problem is that Ariana doesn't agree! "We're all really confused as to why Nathan keeps saying that he and Ariana talk so much," one of Ari's friends told a source. "They don't talk to each other at all." Yikes! Not to worry, though, Ari's bud also reveals she "only has good things to say" about Nathan!
