Post Malone is going all in on this country thing, so much so he popped on stage during the last few songs of Dwight Yoakam's set in LA on Thursday and came back for the first song on the encore.
Posty sat in on so many songs during Dwight's hometown gig someone on Twitter said, "We went to a Post Malone concert and a Dwight Yoakam concert broke out."
