Rumours had been circulating that the pop star would cancel her tour if she had to leave her sons at home, reports Us Magazine.
A message was posted on her official Web site, that read, "Both Sean Preston and Jayden James will, in fact, be joining Britney throughout the duration of her tour."
Spears had considered cancelling the entire Circus tour if her ex-husband, Kevin Federline, pushed for the boys to stay home.
Federline, 30, is the primary guardian of the boys, but Spears has 50% visitation rights.
The Circus tour begins on March 3 in New Orleans, and ends on April 28 in Chicago.
