Gwen Stefani corrected husband Blake Shelton on Thursday during a performance in Tishomingo, Oklahoma after he called her by her maiden name.

"I thought it was Gwen Shelton now," Stefani joked while the singers prepared to perform. 

The newlyweds made an appearance at the Ole Red in Oklahoma, owned by Shelton himself. Shelton performed a handful of songs and the couple performed their duets, "Happy Anywhere" and "Nobody But You."

Shelton and Stefani officially tied the knot on July 3.
