Justin Bieber hit NikeTown for the second time this week, on Friday, just as the video for the pop star's first EDM effort dropped -- "Where Are U Now," with Diplo and Skrillex.

After attending Tori Kelly's album launch party at The Nice Guy Thursday night, where ex Selena Gomez was also in attendance, Bieber took to social media to "sing" the praises of the fellow Canadian, Tweeting, "Good times last night. Hey@ToriKelly do u ever miss a note? She is crazy talented. Congrats on the album @ToriKelly. Loved when u sang oceans. Might of [sic] teared up."

Speaking of crazy talented, we love Biebs' latest single -- such a departure from his usual top-40 style ... What do YOU think?
