Singer Blake Shelton says it is still hard to believe that Gwen Stefani is in love with him.
The 40-year-old musician feels blessed that he is in a relationship with the "Used to Love You" hitmaker, reported Entertainment Tonight.
"I still can't believe it. I think that she must have some vision problems. Maybe she needs help," Shelton joked.
Shelton said he has always been a fan of Stefani's few songs but that time he had no clues that it was sung by the 46-year-old songstress only.
"I've always known 'Hey Baby,' I didn't know she sang that freaking song. I'm like Wow, that's you? That's you and we've kissed?"
The couple recently performed together at Stefani's Detroit concert, singing their duet, "Go Ahead and Break My Heart.
