Justin Bieber has assured Florida fans he won't be canceling his Orlando concert following last weekend's (12Jun16) nightclub massacre.

The Baby singer is scheduled to perform live in the city later this month (30Jun16), and he insists the show must go on despite renewed security fears following a tragic weekend there.

Just a day after singer Christina Grimmie was shot and killed by a deranged fan at a post-gig meet-and-greet in the city, 49 people lost their lives when a gunman opened fire inside the Pulse nightclub.

Bieber broke down onstage in Winnipeg, Canada as he dedicated his song Purpose to Grimmie on Monday night (13Jun16), and on Thursday (16Jun16) he made it clear the LGBT community in the city is in his thoughts too.

In a simple tweet he wrote: "For all those asking no I won't cancel the Orlando show. I stand with Orlando in support. Love you Orlando! #OrlandoStrong."
