Gavin Rossdale allegedly cheated with his and Gwen Stefani’s nanny, and it cost him his marriage. Gwen moved on this summer, and is now dating her fellow Voice coach Blake Shelton. The two have shared their PDA on social media, so Rossdale has no doubt become privy to their romance.

How do you suppose Gavin Rossdale will feel if and when Gwen Stefani and Blake Shelton buy a home together? The two are seriously talking about it, so it’s a very real possibility.

In Touch Weekly reports that Gwen and Blake are looking to buy a home in Oklahoma, where Shelton lived with ex-wife Miranda Lambert.

“Gwen and Blake are thinking about buying a love nest! Gwen loves Oklahoma and she actually thinks it would be a great place for her boys to grow up,” a source tells the publication.

The No Doubt singer and Gavin Rossdale are parents to three boys. Kingston is nine, Zuma is seven, and baby Apollo is only a year old.

Gwen Stefani and Blake Shelton talk big, but then they pull in the reins, for fear they are rushing things.

“Every time she and Blake talk about moving in, they always seem to decide that it’s too soon for both of them,” the source adds.

“That said, all the traveling, hotels and suitcases are becoming a major inconvenience, so they’re trying to think of it less as moving in together and more of buying a convenient place for them to hang out!”

That might work well for Gwen Stefani and Blake Shelton–allowing a place for them to become a family with Gwen Stefani and Gavin Rossdale’s boys.

Do you expect Gavin Rossdale might become envious of Blake Shelton if he and Gwen buy a home in Oklahoma together?
