Another weekend of brisk ticket sales for Faith Hill [ tickets ] and Tim McGraw [ tickets ]'s upcoming "Soul2Soul II" tour has led to more dates on the country stars' itinerary.

Demand in St. Paul, MN; Jacksonville, FL; and Philadelphia caused organizers to roll out a second night in those cities, as well as a third show in Los Angeles, tickets for all of which are already on sale.

Also new to the schedule is a second performance in Phoenix, and the tour's first stop in Oklahoma City, OK. An on-sale date for tickets to the new Phoenix show wasn't available at press time, but tickets for the Oklahoma City show will hit the box office on Saturday (3/11), as will those for a previously announced second night at New York City's Madison Square Garden.

The updated itinerary is included below.

Members of Hill's and McGraw's respective fan clubs have access to tickets before the general public. More information is available at the tour's official website.

Hill is backing her 2005 release "Fireflies," which last August entered The Billboard 200 album chart at No. 1. The 14-track set spawned the hit single "Mississippi Girl," as well as "Like We Never Loved at All," a duet with McGraw. Earlier this month, the latter cut earned the couple a Grammy for Best Country Collaboration with Vocals at the 2006 Grammy Awards ceremony.

McGraw is gearing up for the March 28 release of "Tim McGraw [ tickets ] Reflected: Hits Vol. 2," a best-of set that also includes the new tracks "When the Stars Go Blue" and "I've Got Friends That Do." His most recent collection of all-new material is 2004's "Live Like You Were Dying."
