Pop singer/songwriter Colbie Caillat [ tickets ] will follow the August release of her sophomore album, "Breakthrough," with a fall tour of North America.

The two-month excursion, which kicks off Sept. 17 in Anaheim, visits clubs and theaters in 24 major markets across the nation and parts of Canada. Fellow pop rocker Howie Day will accompany Caillat on the trek, which currently concludes Oct. 23 in Dallas. The full schedule is shown below.

"Breakthrough," Caillat's second studio set, will hit shelves Aug. 25. The 12-track album features new material written by the California-based songstress with the help of co-writers Rick Nowels, Jason Reeves, John Shanks and "American Idol" judge/songwriter Kara DiGuardi. A deluxe edition of the disc will include an extra five songs and a DVD.

"On this record, I was able to contribute a lot more of my production ideas into the recording," Caillat explained in a press release. "I had a better sense of how I know the songs should sound and feel, and what instruments should be added or taken away from them. Because I didn't get to do that on 'Coco,' to really be able to make these songs completely my own was a special experience for me."

The 24-year-old SoCal native was discovered with the help of her MySpace page, leading to her major label debut, "Coco," which surfaced in 2007. The album debuted at No. 5 on The Billboard 200, while "Bubbly," the lead single, landed at No. 2 on the magazine's Pop 100 chart.
