Norah Jones [ tickets ] will launch a four-week tour in April to support her latest studio release, "Not Too Late," which hit stores Tuesday (1/30).

According to her publicist, Jones is the best-selling female artist of the 21st century, with more than 15 million in sales over the course of the decade, and 30 million worldwide.
