During the opening night of her Las Vegas residency grandeur at the Zappos Theater at Planet Hollywood, Wednesday (June 27), Gwen Stefani changed outfits plenty of times. That's no surprise, as the pop star is a renowned clotheshorse. However, she did manage to sneak in a little bit of vibe from her boyfriend, Blake Shelton, as at one point she donned a full-on cowgirl outfit complete with fringe and boots.

In an interview with Extra TV following the show, Stefani confirmed the outfit was a nod to Shelton—and even admitted that her absolute favorite moment of the evening was "Probably standing in that cowgirl outfit in front of Blake."

She further clarified: "That part of the show, for me, is like my super love note, my 'I'm so grateful, this is how much you've influenced me and gave me life.'"

"He's part of my journey," she added. "It's amazing that he was there."

Shelton was apparently in the middle of taping the blind auditions for the next season of The Voice this week, and was (adorably) struggling to figure out how to make it to his girlfriend's opening night.

Stefani assured him she understood: "I was like, dude, just come on the weekend, it's fine," she said. "And he was like, 'I'm not gonna miss it!' He was so serious about it!"

Shelton not only showed up, he also played the perfect gentleman and sent his girl a beautiful flower arrangement, complete with a love note complimenting her on all her hard work prepping for the residency.
