The concert was scheduled for tomorrow in Vorst Nationaal. The event was cancelled over safety concerns, a decision made to protect the safety of Carey's crew and fans, a statement said:
"I love my fans in Brussels and at this time I am being advised to cancel my show for the safety of my fans, my band, crew and everyone involved with the tour. I hope to see you soon and send my prayers and eternal love, laughter and light to my Lambs", the star posted on Twitter.
Concert organisers Live Nation confirmed the cancellation on their website. Ticket holders can claim their money back.
