Over the weekend, Gwen Stefani joined boyfriend Blake Shelton at his pal's wedding at River Ranch Stockyards in Fort Worth, Texas.
During the reception, Stefani was pulled onto the dance floor and got down to her own song, "Hollaback Girl"!
The singer tweeted the video with the banana emoji and captioned it, "6.2.18 #hollabackgirl #bestreceptionever."
