Britney Spears will begin a tour next spring, produced by AEG Live. Sources say the trek will likely be international in scope, as were recent AEG Live-produced outings by Bon Jovi and Justin Timberlake.

Spears last toured in 2004, grossing more than $34 million, according to
Billboard Boxscore.

The artist will be out in support of her new album, "Circus," due Dec. 2 via Jive. First single "Womanizer" is expected to leap into the upper reaches of the Billboard Hot 100 this week after first-week download sales are factored into the chart.
