Katy Perry is packing up the cherry Chapstick and hitting the road.

The smooch-happy pop star is embarking on her first world tour next year in support of her debut album, One of the Boys, which contains her smash-hit single "I Kissed a Girl," as well as...some other songs.

Perry's 50-city global jaunt will touch down in large clubs and small theaters from Arizona to Amsterdam. She starts off Jan. 23 in Seattle, heads to Europe a month later and then returns to the states before wrapping April 28 in St. Petersburg, Fla. Her website connects all the itinerary dots.

Danish pop group Alphabeat will open for Perry on her North American dates, while electronic rockers 3OH!3 will join her overseas.
