ScHoolboy Q and A$AP Rocky have been buddies and collaborators for a while.

But that may all change after Q went to China and saw A$AP in his underwear.

"On the real, on the real. Stop texting me. Don't call me," ScHoolboy said after seeing Rocky in Calvin Klein ad. " No my nigga pause, I don't care how much they paid you. That nigga just thought he could post that shit in China."

We're pretty sure Q is joking and he didn't really lose Rocky's number. Nevertheless, is underwear modeling overseas a legit way to make cash?
