The House of Blues said Thursday that her concert with The Daylights will now be held May 11.
Perry, 24, is best known for her hits "Hot 'N Cold," "You're So Gay," and "I Kissed A Girl," which earned her a Grammy nomination for best female pop vocal performance.
Perry is also well known for her unique style and lavish stage presence. Afraid of nothing, Perry is comfortable in a variety of unique outfits that have certainly turned heads -- including a banana, a carousel and a football uniform. The latter of which she proudly wore while straddling a cannon emblazoned with her name. See photos of Katy Perry here.
Reps for the club said all tickets purchased for the March 21 show will be honored for the new date.
