Britney Spears, who turned 22 on Tuesday, has been teasing fans with her one-off club shows and TV performances, but now she's finally going to go all the way with a full-on tour for In the Zone.

The pop princess announced Tuesday (December 2) that she'll kick off her tour March 2 in San Diego, hitting 25 North American cities and wrapping things up April 12 in New York.

"It's always special to be able to go on the road and give something back," Spears said in a statement. "I'm especially looking forward to bringing my tour to new markets and performing in front of fans that may not have had the opportunity to see any of my previous tours."

Spears last toured in 2002 on the Dream Within a Dream world tour that ended in July of that year with an abruptly shortened final stop in Mexico City (see [article id="1456371"]"Britney Says Lightning Storm Forced Her To End Mexico Show"[/article]). Her North American legs of the highly theatrical trek grossed $43.7 million.

Tickets for the new tour go on sale December 13. A portion of all ticket sales will benefit the Britney Spears Foundation. Venues have yet to be announced.
