The announcement of pop singer Shawn Mendes' new tour nearly broke the internet. 

The top trending hashtag on Twitter Wednesday afternoon was #IlluminateWorldTour after Mendes began announcing the cities on the calendar for his highly anticipated world tour. However, fans will need to be quick if they hope to snag some of the coveted tickets. 

Mendes, the 18-year-old Canadian singer who turned a surging Vine following into a major label record deal with Island Records, got playful in announcing which cities he would be playing on the Illuminate World Tour. In a series of Snapchat videos, Mendes filled fans in on the list of cities three at a time, using animal filters to bring a little levity to the announcement. The reveal was part of a partnership with iHeartRadio.  

Among the U.S. cities on the list are Washington D.C., Boston, Pittsburgh, Nashville, Cleveland, Chicago, Miami, Orlando, Atlanta, San Antonio, Houston, Tampa Bay, Glendale, Denver, Oakland, Los Angeles, New York, Denver and Dallas. 

Mendes will also be getting outside of the U.S. for an international leg of the tour. The tour will stop at Barcelona, Zurich, Munich, Stockholm, Oslo, Copenhagen, Berlin, Vienna, Madrid, Lisbon and Amsterdam, among others. 

Tickets for dates on the tour will go on sale on Sep. 16 at 10 a.m. local time for European dates and on Sep. 24 at 10 a.m. local time for North American dates. Links for purchasing tickets to all dates will be available on Mendes' website here with information about various fan and American Express pre-sales. Ticket prices start at $47.50 for North American dates.

If tickets sell out, which is likely, fans can still buy them through another vendor. Browse resale tickets on a third-party site like StubHub or search Craigslist for fans looking to unload extra tickets. But be wary of scalpers with marked up prices and make sure you're spending your money wisely by looking on Facebook fan groups for tickets, prioritizing physical tickets over PDFs and negotiating prices, according to Showbams.com.
