Stefani went full-on glam for the show, donning a black turtleneck top, shiny patterned mini skirt and thigh-high boots, keeping her platinum blond tresses pulled back into a messy top knot. The 40-year-old country crooner was rocking a much more casual look, sporting comfy blue jeans and a gray button-down shirt.
Naturally, the No Doubt frontwoman took to Snapchat to share some behind-the-scenes pics and videos, snapped backstage at the iconic venue. Judging by the photos, which included "A cake for Blake," stamps with the couple's faces and red solo cups laid out to form the letter "B," it appears the backstage party was a blast!

Although Shelton isn't an avid Instagram user -- his page only has six pics! -- he couldn't help himself from sharing a sweet photo of himself chatting with an elderly fan after the show.
"Hope I'm still showin up to country shows at 96!!" he captioned it.
Earlier this week, Stefani was a guest on The Tonight Show Starring Jimmy Fallon, where she joked about some of her and Shelton's differences.
"I think he's quite miserable when he's not in the woods or, like, somewhere in camo," she said of Shelton not being a city guy. "He really likes to be camouflaged."
"I know that for me I just go anywhere, and I know I'm gonna get hounded for pictures or whatever," she continued. "I don't mind, you know what I mean? For him, he's just not used to that, like I said. He's in the woods most of the time but, yeah, we went [to Disneyland recently]. It was crazy. It was, like, a billion people there."
