[artist id="3274550"]Katy Perry[/artist] is taking her act on the road in 2011 for her California Dreams Tour. The "Teenage Dream" singer will kick off the tour on February 20 in Lisbon, Portugal, with the European dates wrapping up April 5 in Glasgow, Scotland. More info about the tour can be found on her website. No opening act has been announced yet.

Perry hasn't yet updated her site to reflect any of the dates for the U.S. stops on her tour, but she did tweet, "P.s. My dates in the USA, AUS & MORE are being put in soon of COURSE! Don't you worry...."

Perry has been clear that she [article id="1647784"]wants the tour to be a spectacle[/article]. "I hope that it's going to engage all of your senses: sight, sound, smell, taste, touch," she explained at the VMAs last month. Previously she explained that the [article id="1646972"]tour will be a feast for the eyes[/article].

"I guess I'm looking forward to making music videos on this new album ... and I'm really excited about incorporating the look and the idea of some of the songs on tour and making a massive production of it," she said. "I'm gonna want a lot of visuals. I want it to be 10 times better than when I was on tour last."

In addition to announcing her tour, Perry also tweeted a teaser video for her forthcoming [article id="1649506"]"sparkling" "Firework" music video[/article]. The teaser shows stills of Perry at a courtyard party in a European city. Other shots from the video show revelers dressed in underwear jumping into a pool. But the video takes a more serious turn when it shows those who have overcome adversity finding their inner fireworks with real fireworks blasting behind them.

Perry didn't go into details about the clip's concept, but she did thank the people she worked with on Twitter. "Not gonna stop shooting till the sun comes up cause we are a LIGHT in a dark place!" She wrapped the shoot on September 30, saying, "I want to thank all the magical people that brought their sparks to this video the past few days ... your light reminded me of my purpose."
