AceShowbiz - Miranda Lambert surprised everyone when she announced her marriage to Brendan McLoughin, but how does her ex-husband, Blake Shelton, feel about this? According to HollywoodLife.com, the "God Gave Me You" singer and his girlfriend Gwen Stefani pay no mind to the Pistol Annies member's surprise wedding.

"Blake and Gwen really don't care either way about Miranda's marriage," a source tells the gossip site. "It was much easier for Blake to move on than Miranda. It took her a very, very long time to really get over Blake, and it hurt so badly to see Blake move on quickly with Gwen, but she's very happy now."

Even though "The Voice" coach allegedly doesn't really care about the marriage, it's still a relief for him to see Miranda tying the knot. "To see Miranda get married is almost like a relief to him," the source goes on explaining. "She was a big part of his life for quite awhile and only wants good things for her, but he's not paying attention at all. He's happier than ever with Gwen."

A second source tells Us Weekly that Blake wasn't told in advance about Miranda and Brendan's wedding. "Blake found about the wedding at the same time everyone else did," the insider spills to the publication.

Miranda announced her marriage to Brendan on Saturday, February 16 through an Instagram post. Along with pictures from their nuptials, she wrote, "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." The couple reportedly tied the knot in January in Nashville.

Following the announcement, the couple was seen stepping out in New York City. Walking hand-in-hand, they rocked matching leather jacket and flaunted their wedding bands.
