Gwen Stefani who? The 51-year-old No Doubt front woman outright told her new husband Blake Shelton, 45, that she would like to be called ‘Gwen Shelton’ now in an adorable exchange that’s gone viral. On Thursday, July 15, the married stars were performing together for the first time since tying the knot at the Ole Red bar when Blake — who was sitting beside his wife — said to the crowd, “We have Gwen Stefani singing in Tishomingo, Oklahoma,” which earned a big applause from the audience.
