Shania Twain has added nearly 20 more dates to her upcoming Rock This Country tour.

The country superstar announced her first tour in 11 years during an appearance on Good Morning America on March 4. She also revealed it will be her last full-scale tour. “I feel like I’m ready to hang my hat up in that regard,” Twain explains. “I just really want to go out with a bang.”

The tour is set to kick off June 5 in Seattle, and when tickets went on sale for the initial 50 dates on March 13, demand was so high that Twain decided to add a second leg to the road trek. The Rock This Country tour was originally slated to end on Aug. 23 in California, but Twain has announced another run of dates that will begin Sept. 12 and run through Oct. 11, taking in 19 additional shows before wrapping in Ontario, Canada. Singer-songwriter Gavin DeGraw will be Twain's special guest on most of the fall dates.

Twain hasn't been entirely away from the spotlight since her last tour. She recently released Shania: Still the One Live From Vegas, a CD/DVD package that captures her Las Vegas residency that ran from 2012-2014. In an interview with Taste of Country Nights radio, Twain shares fans who saw her in Vegas can expect “a completely new show, an entirely new theme than the Las Vegas show.”

She adds, “It’s just gonna be a real, kickin’, hard-hitting, fun party show."

Tickets for the additional Rock This Country tour dates go on sale on May 15, with a limited number of exclusive VIP packages available. For more information, visit Twain’s website.
