EXCLUSIVE: See Blake Shelton's Reported New Home in Oklahoma -- and Gwen Stefani's Already Been There!

Blake Shelton reportedly has built his dream home, and he's already welcomed a special visitor.

ET has learned that Shelton is close to completing his new home -- only an hour away from his hometown of Ada, Oklahoma -- and, in late October, Shelton gave his new girlfriend, Gwen Stefani, the grand tour.

"Blake gave Gwen her biggest taste of country life," a local resident and friend of Shelton's tells ET. "They ate home cooking at his favorite diners and Blake took her to his new lake house. There's no Starbucks around here. If she's still around after that then it must be serious!"

Shelton's expansive, multi-level abode sits on the shore of Lake Texoma, which crosses the state line between Oklahoma and Texas.

The estate includes a private dock at the end of the large garden, and a balcony that overlooks the lake.

A longtime friend of the Shelton family told ET that the "Sangria" singer stayed with his 46-year-old girlfriend at the new house "instead of [his] marital home, which tells you how much respect he still has for [ex] Miranda [Lambert]."

Shelton and Lambert, 32, divorced in July, three months before Shelton's rep confirmed he was in a relationship with Stefani -- who is also going through a high-profile divorce with her ex, Gavin Rossdale, with whom she split in August.

While it might be the perfect home for Shelton, some locals aren't as excited to have the star living nearby.

"All we want is for peace and quiet,” a neighbor told ET. “There will be some disagreements along the road if it starts to get busy with fans turning up at his door."

Although it seems Shelton is already trying to ingratiate himself with the people of Oklahoma with some impressive heroics. On Friday, Shelton rescued four guys who had gotten stuck in some deep mud along a river bank by pulling them out -- and their vehicle -- to safety.

Check out the video below to hear Shelton modestly downplay the heroic rescue when he spoke with ET on Monday.
