One person who is not focused on Blake Shelton and Gwen Stefani's love life is Shelton's ex-wife Miranda Lambert.

The country singer and her boyfriend Anderson East are reportedly getting serious and Lambert is focused on her relationship and working on new music.

"Miranda and Anderson are talking about moving in with each other,"a source told E! News. "It's getting pretty serious. They want children and have shared their thoughts with each other on that subject."

While Lambert, 32, has yet to release any new music since her divorce this summer, her ex has released several songs about their split and his new girlfriend.

Lambert isn't fazed by the telling tunes, the source says.

"Miranda is aware of what country artists do when creating new music," E! reports. "She is not upset at the lyrics because she knows it's just how it goes, especially as a country artist."

The source added, "She is always thinking and currently working on new lyrics and song ideas and many of those ideas steam from the past, present and future experiences."
