Even if the pregnancy rumors are true, Blake Shelton made it clear that marrying Gwen Stefani is still not in the picture. After two failed marriages, the country singer has resolved that tying the knot isn't for him.

A source revealed that when asked about taking their relationship to the next level, Shelton expressed hesitation. The source said, "When someone asked if they were going to get married, Blake became a little awkward. He muttered something about how Gwen's divorce wasn't finalized yet, but it was obvious there was more to it than that."

Shelton was first married to Kaynette Williams but their relationship ended after he met Miranda Lambert who eventually became his second wife. Unfortunately, the country singer's second marriage failed too leading to their highly-publicized divorce last July.

"He's confided to a few friends that he doesn't think it's for him," the insider related. "He cares a lot about Gwen and is having a great time with her, but knowing his history, that he hooked up with Miranda when he was married to Kaynette and his marriage to Miranda imploded, he's just not convinced a traditional marriage can work for him."

While marriage is not in Shelton and Stefani's cards, moving in together is a possibility. Another report claimed that Stefani plans to move out of her California home and join Shelton in Oklahoma.

A separate source said, "For the longest time, she's living in the Hollywood bubble, and it's finally popped. If Gavin [Rossdale] okayed it, she would love to move the kids to Oklahoma on a more permanent basis. It's just so much more serene there, and it would be a great place for them to grow up." Stefani has three children with her ex-husband namely Kingston, Zuma and Apollo.

Shelton and Stefani made their relationship public last November 4, just months after Stefani filed for divorce from Rossdale.
