The 40-year-old country singer also gave Gwen the spotlight – who dazzled in a metallic blazer, shorts, and thigh-high boots –  as she rocked out to her hit throwback song, Hollaback Girl.

The 46-year-old songstress documented the thrill on her Periscope, which she posted to her Twitter as she cheered Blake on from the sidelines before she took center stage.
