Blake Shelton Thinks His “Unicorn Girlfriend” Gwen Stefani Is Marriage Material (REPORT)

Even Blake Shelton knows Gwen Stefani is out of his league! Jokes aside, the country crooner is still head over heels with his longtime girlfriend — and hoping to make it official soon.

“Blake jokes with Gwen that she is so hot, and so down to Earth that she is like the unicorn of girlfriends… women like her shouldn’t exist in the real world,” a source close to the couple told Hollywood Life. “Blake knows too that if you find yourself lucky enough to be dating someone like Gwen, you marry her. Gwen is marriage material for sure.”

The pair met on The Voice in 2015 — right after Blake, 41, divorced his ex-wife, Miranda Lambert, and Gwen, 47, was going through a similar split with ex-husband Gavin Rossdale. Fast forward two years, and they look happier than ever. So happy in fact that the couple recently enjoyed a fishing trip with Gwen’s sons Kingston, 11, and Zuma, 8. We assume three-year-old Apollo was napping.

Life & Style previously reported that Gwen is also hoping to expand her family with the “Sangria” singer. And she is trying everything to make it happen. “They’re trying to have a baby first,” an insider said. “That’s their main focus right now. [Gwen’s] determined to have another baby and carry it herself, even though Blake has said it doesn’t matter if they adopt or get a surrogate.”

The source continued, “It might be a baby, or it might be a toddler. But no matter what, they want to have a little girl in their arms by the end of 2017.”

And it looks like Gwen also considers Blake a unicorn boyfriend. “It’s so unbelievable. I love Blake. He’s the most incredible guy. Everybody loves Blake and that’s the thing, there’s no way around it,” she said during a recent appearance on Late Night With Seth Meyers. “He’s just a sparkly, happy, amazing person.”
