According to ET, after accepting the award she simply stated, "I needed a bright spot this year." Earlier that night, she performed her heartbreaking new single, "Bathroom Sink," and seemed to be fighting back tears.

Apparently, during the CMA awards night Miranda rocked the red carpet with a very Stefani-esque pink hairdo. She looked stunning showing off her figure in a form-fitting dress by Versace.

When complimented on her dress, a source tells ET, her stylist said, "See! It is your revenge dress," and Miranda responded, "Absolutely!"

ET's source also spotted a sweet moment between Lambert and her Somethin' Bad duet partner Carrie Underwood backstage at the show. "They hugged and embraced for a long time," the source says. "They spoke quietly to each other with their arms around each other. ... It seemed as if Carrie was comforting her."

Meanwhile, on that night Shelton was also set to perform on stage which marked for the very time that the two would be at the same public event after they have broken up last July. While Underwood and Paisley - the two hosts poked a little fun at Shelton.
