Blake Shelton Thinks Gwen Stefani Has 'Vision Problems'!

Blake Shelton grins as he performs on NBC’s Today show on Friday (August 5) at Rockefeller Plaza in New York City.

The night before, the 40-year-old country singer stopped by Late Night With Seth Meyers to perform his hit “She’s Got a Way With Words” and discuss his relationship with girlfriend Gwen Stefani.

“I think she must have, like, some vision problems,” he laughed. “Maybe she needs help.”

He went on to discuss how the lovebirds are still learning each other’s music.

“I’ve always known ‘Hey Baby,’” he added. “[But] I didn’t know she sang that freaking song. It’s like, ‘Wow. That’s you? That’s you, and we’ve kissed? Wow, that’s amazing!’”
