Last week, we learned that Katy Perry will be stopping in Grand Rapids to play Van Andel Arena as part of her Prismatic World Tour. Katy is scheduled to take the stage at the Van Andel on Aug. 10, but up until now, that's all we knew.

Today, more details about the show have been announced, including a special pre-sale for Citi card holders and Perry's Facebook fans.

A special pre-sale for Citi card owners started this morning through their Citi Private Pass program.

Katy's Facebook fans can look forward to a special promotional code for tickets to be released to them on Jan. 23 (Thursday), which will give them a chance to pick up tickets to see her before they go on sale to the general public.

Tickets go on sale to the general public on Monday, Jan. 27 at 10am and can be purchased at the Van Andel Arena box office, all Ticketmaster locations, and online at Ticketmaster.com.
