“Over You” singer Miranda Lambert and No Doubt star Gwen Stefani have more in common than NBC “The Voice” coach Blake Shelton: Both women know what it's like to have a broken heart. Lambert was able to relate when she watched Stefani perform the breakup anthem, “Used To Love You,” live at the American Music Awards on Sunday, Hollywood Life wrote in an exclusive report Monday.

Lambert, 32, could “relate” to the lyrics. “Used To Love You” was written after Stefani, 46, discovered that her then-husband, Gavin Rossdale, reportedly cheated on her with their children’s nanny. “She can totally relate to her new song,” an insider told Hollywood Life. “Despite the fact that Gwen is dating her ex-husband, Miranda has always been a fan of her music.”

In part of the song Stefani sings: “Suitcase, Band-Aids/ Pulling back out the driveway/ You go, I'll stay/ You can keep all the memories/ I thought I was the best thing that ever happened to you/ I thought you loved me the most.”

Lambert was impressed with Stefani’s emotional performance Sunday. “She did see Gwen’s performance last night and thought she did an excellent job,” the insider said. “She can sympathize with Gwen with regard to the words in ‘Used To Love You.’”

Shelton, 39, seemingly tweeted his support for the No Doubt singer before she took the stage Sunday. “Prepare for greatness,” he wrote. The couple did not walk the AMA red carpet together, even though their high-profile relationship has been widely talked about.

Stefani’s rep confirmed they were dating Nov. 4, the same day of the CMA Awards. “Gwen and Blake are longtime friends who have very recently started dating,” Stefani's spokesperson told Us Weekly.

But when it comes to talking about their relationship in public, she remains tightlipped. When Ellen DeGeneres asked her about Shelton’s kissing abilities, the star blushed and turned away. She did praise him for his knowledge of music, though. “He knows every single '80s song. He literally is a musical jukebox. He knows everything about music,” Stefani said.
