Well, this isn't cool. Not cool at all.
And while Zac quickly reunited with Michelle after the pics exploded on the interwebz, you couldn't possibly think he wasn't going to confront Bieber!
So while BOTH boys were out and about in Ibiza, it looks like Zac finally got his moment alone with Justin…
…and it doesn't look nearly as terrifying and brutal as we would've expected.
Does this mean these two boys are buddies??? Considering all the partying trouble Zac has suffered recently, Biebsy boy might not be the best company to keep.
We sure hope Zac was just measuring the size of Justin's neck to see if he could fit in some dress shirts he no longer needs!
