Ariana Grande's Ex, Nathan Sykes says Ariana Left him out of 'THANK U'

One of Ariana Grande ' s famous
exes is beyond thrilled he didn' t
make the cut for her new hit song
about past romances ... so much
so , he couldn' t contain his sense of relief .

We got Nathan Sykes of The Wanted Wednesday at LAX, where we asked how he felt about not being named in Ari' s song" thank u, next " .. . which name- checks the likes of Big Sean , Ricky Alvarez, Mac Miller and , of course, Pete Davidson.

Nathan , who dated Ariana briefly in 2013, hasn' t heard the track yet . .. but after we described it , he breathed a genuine sigh of
relief. Seriously , you have to see his reaction - - pure joy .
The song' s basically about what AG ' s learned from each of her ex -BFs . So , we had to ask Nathan what HE learned from her .
We' re not saying he shaded her -- he actually showed Ariana a lot of love here - - but let' s just say there was a looong pause after our
question .

As for her being single now ? Nate ' s good .
