Country singer Garth Brooks will not be without fellow country singer and lady love Trisha Yearwood as he embarks on a nine-gig tour – she will open each concert for him.

Garth Brooks single-handedly sold out nine shows at the Sprint Center in Kansas City, Mo. on Saturday, moving nearly 160,000 tickets in less than two hours at ticket outlets and via online and telephone sales, reports Billboard.com.

Trisha Yearwood, his wife of nearly two years and a country star in her own right, confessed to CMT.com that the decision to support Brooks on his tour was spontaneous, made during Saturday’s ticket-selling frenzy.

“I've never been involved in anything like it,” Yearwood told CMT.com. “Garth was actually cooking breakfast for everybody, and the cell phone was on speaker. I've never seen anything like this before, where you're thinking, ‘It'll be one show, and if it's two, then I'll be really lucky.”

The singer went on to say that it actually turned out to be one sold-out show after another: “It was amazing, and they just kept going and kept going and kept going.”

As a result, she will be Brooks’ special guest when he plays Kansas City Nov. 5-12 and 14.

According to Billboard.com, these will be the most shows Brooks, 45, has played in nearly a decade.

The last time he toured, in the late 1990s, in support of his 1998 Capitol release “Sevens,” the country singer broke all U.S. touring records. His tour, stretching over a three-year period, grossed more than $105 million and drew close to 5.5 million people, according to Billboard.

A three-disc boxed set titled “The Ultimate Garth Brooks” is scheduled for a Nov. 6 release via Pearl Records, his own label. The set will contain a 34-track, two-CD greatest hits retrospective with four new songs and a DVD with videos (many of them recently filmed) for all tracks on the CDs.

Trisha Yearwood will release a new album, “Heaven, Heartache and the Power of Love,” on Nov. 13. She had initially told her husband she couldn’t participate in his concerts but the unexpected buzz convinced her to rethink her schedule.

“I was sitting there and thinking, ‘I want to be a part of this,’” Yearwood told CMT.com. “I basically said, after these nine shows sold out in less than two hours, ‘Why wouldn't I want to sing for 150,000 people - and get to be with my husband every night?’ So I said yes.”
