Miranda Lambert earned a coveted spot as an opening act for a couple of shows on George Strait's farewell The Cowboy Rides Away Tour, including a recent stop in San Diego. But in addition to taking the stage before the country music icon, the songstress also got to perform with him for two of his biggest hits.

When Strait began singing his 2007 hit 'How 'Bout Them Cowgirls,' Lambert returned to the sold-out crowd to sing with him on the tune, resulting in a frenzied crowd who hung on to every word.

Getting to sing with one of her own musical heroes was a dream come true for the 'Automatic' singer, who recalled first seeing him perform when she was only 15 years old, followed by her young boyfriend scoring 12th row seats when she was 17.

“From the back row of Texas Stadium to the 12th row, and now I’m standing here singing with the King,” Lambert said, clearly soaking in each moment. The two then launched into a duet version of Strait's 2001 song, 'Run,' before Lambert exited the stage to thunderous applause.

Eric Church and Martina McBride have already joined the King of Country on his farewell tour. Other artists scheduled to appear include Little Big Town, Vince Gill, Sheryl Crow, Merle Haggard, Tim McGraw and Faith Hill. Most artists will appear for his final concert on May 7 in Arlington, Tex. All shows are sold out.
