Usher's Upcoming Tour Struggling with Lackluster Ticket Sales?

Usher is preparing for his upcoming North America trek, dubbed the The UR Experience Tour, however ticket sales reportedly have been lackluster.

Sources tell the New York Post's Page Six that the crooner's 27-city outing is said to have sold only a small portion of the available seats.

“Usher’s sales will be fine in New York, Los Angeles, Chicago and Toronto, but he’s selling so badly in other markets that the good ones can’t offset the bad ones,” says one source.

In addition, tour promoter Live Nation could potentially lose $5 million due to soft ticket sales, which some insiders attribute to the lack of a strong opening act -- August Alsina and DJ Cassidy are currently on the roster.

The news comes on the heels of Usher delaying the release of his eighth studio effort, which was initially expected to arrive this fall.

As previously reported, the singer is scheduled to kick off the tour on November 1 in Montreal. He'll travel to Los Angeles, Atlanta, Detroit, Toronto, Philadelphia, Boston, and Las Vegas before concluding on December 24 in Tampa.
