AceShowbiz - Considering how long Blake Shelton and Gwen Stefani have been dating, the country singer should have gotten used to seeing his beautiful girlfriend at this time. However, he actually still can't believe how gorgeous the No Doubt singer is despite dating for three years.

During an interview with Entertainment Tonight on the red carpet at "The Voice" taping in Los Angeles, he talked about their recently-released music video for "You Make It Feel Like Christmas". When fellow coach Jennifer Hudson asked him how "gorgeous" she looked in the visuals, the award-winning singer replied, "How gorgeous does she look all the time? It's unbelievable."

"Right now, wherever she is, she looks gorgeous, whatever she's doing," he continued, before playing coy when asked whether or not he considered Gwen his personal "forever."

This is by far the first time Blake has gushed over the blonde beauty. When he stopped by "The Ellen DeGeneres Show" earlier this month, the "God Gave Me You" singer opened up about how he still couldn't believe she agreed to date someone like him. Pointing at a picture of them kissing backstage at her Las Vegas residency, he said, "I can't believe that she's with me. What is wrong with her? There's something wrong with her!"

Blake and Gwen started dating back in 2015 after they first met on the set of "The Voice". Since then, they have been pretty much inseparable, though some of his friends were doubting their relationship at first. "When we first started seeing each other, friends of mine would be like, 'What the hell is that all about?' " Blake said in an interview with PEOPLE last June. "But if you ever had a chance to be around us together, it does make sense. People do like us together."
