Miranda Lambert may have surprised people with her wedding to Brendan McLoughlin, but her ex-husband Blake Shelton reportedly doesn’t care about her new relationship and is happy their marriage is over.

Shelton, who finalized his divorce with Lambert in 2015, began dating Gwen Stefani that same year following her split from husband, Gavin Rossdale. Meanwhile, the “Tin Man” singer carried on relationships with Anderson East and Evan Felker before marrying McLoughlin.

Seeing as Shelton’s marriage with Lambert ended over three years ago, those close to the “I’ll Name the Dogs” singer told People he has no interest in his ex-wife’s life. “Their marriage ended and he moved on. Ever since, he is grateful every day,” the insider revealed.

Shelton is reportedly especially happy in his relationship with Stefani. “Blake is crazy about Gwen, and all he sees are hearts in his eyes every day,” the source shard.

Insiders previously told Us Weekly, Stefani and Shelton “are going to be announcing their engagement very soon” after more than three years of dating.

“Blake has always wanted to marry Gwen, but she’s always been extremely cautious because she has three kids to be mindful of,” the insider told the publication.

Lambert first shared news of her marriage to McLoughlin over the weekend on Instagram by posting two photos from their wedding. “In honor of Valentine’s Day I wanted to share some news. I met the love of my life. And we got hitched! My heart is full. Thank you Brendan McLoughlin for loving me for.... me. #theone,” she captioned the pictures.
