The opening acts set to join Justin Bieber on the closing dates of his 2017 run of the Purpose World Tour were only announced last week, but...uh, welp, he's done.

TMZ broke the news on Monday afternoon (Jul. 24): Justin's ending the final leg of his tour early, canceling 14 shows beginning with his Arlington, TX stop this weekend. It's "unclear" why he made the decision to scrap the final dates, but one 'tour source' says it's because he's "just over it."

The Purpose World Tour kicked off in Seattle last March and stretched around the world over the past year, with just over a dozen shows left to go.

The future tour stops included Minneapolis, East Rutherford and Toronto. Kehlani, Martin Garrix, Migos and Vic Mensa were meant to open those shows.
