Chris is currently on his Carpe Diem tour in Europe but according to the Huffington Post, event organizers Hits & Jams Entertainment announced that Chris had backed out from the event due to the negative reaction.
However, Gossip Cop has since claimed that Chris was never actually committed to the gig.
A source close said that Hits & Jams Entertainment has been "untruthful" about Chris' involvement.
Chris and his reps are yet to address the concert cancellation.
