Blake Shelton celebrated Gwen Stefani’s big milestone. On Saturday, the “Sweet Escape” songstress took the stage for her first performance at the Grand Ole Opry and her husband was there to celebrate the moments when she got not one, but two, standing ovations from the crowd. “I am absolutely beside myself right now… Congratulations @gwenstefani on not one but TWO standing ovations for your Grand Ole @Opry stage debut!!! That was an incredible moment to witness,” the 46-year-old wrote.
