Miranda Lambert is leaning on her fellow country gals for support following news that her ex, 39-year-old Blake Shelton, has officially moved on with his fellow Voice coach, 46-year-old Gwen Stefani.
Carrie Underwood, in particular, appears to be a good friend when in need.
"[Miranda] was talking after the awards to Carrie and they hugged and embraced for a very long time," a backstage eyewitness tells ET about the pals' interaction at the CMA Awards in Nashville on Wednesday night. "They spoke quietly to each other with their arms around each other. It seemed as if Carrie was comforting her."

Wednesday night was obviously a difficult time for the 31-year-old singer. Just hours before the show -- the first high-profile function the exes have both attended since their shocking split in July -- reps for both Blake and Gwen confirmed that they are officially dating. The surprising couple was also spotted holding hands while walking out and about in Nashville, and certainly didn't shy away from the cameras.
"Miranda tried to seem happy, but you could tell she was hurting," the eyewitness adds about the "Bathroom Sink" singer's demeanor. "It was a great night for her because she won an award, but still hard for her."
Still, Miranda took the time to send Carrie flowers before her big co-hosting duties.
"I want everyone to know how sweet @mirandalambert is!" Carrie tweeted on Wednesday. "She sent flowers & vino for tonight! The Thelma to my Louise."
Earlier this week, Miranda's pal Kellie Pickler talked to ET about the "Nashville Girls Club," which aside from Miranda and Carrie, includes Taylor Swift.
"You support each other," Kellie said, when ET caught up with her to talk about her new CMT reality series, I Love Kellie Pickler. "When you're feeling down you have your friends that you call, and they'll build you up. And when they're feeling down you build them up ... We celebrate each other and everything great that's happening in all our lives."
Miranda and Blake also have mutual friends that have come out in support of the "Mama's Broken Heart" singer. Singer Ashley Monroe talked to ET in late July, after Miranda and Blake both promoted her new album, The Blade, following their divorce bombshell. Miranda made her first public appearance on stage at Ashley's album release party, where the friends embraced during a rendition of "Heart Like Mine," which they wrote together.
"It means a lot to me that she's ever up on stage with me," Monroe said. "She's a very brave person and I look up to her a lot for it."
Ashley, Miranda, and songwriter Jessi Alexander, recently took a girls' trip, which Miranda happily Instagrammed about last month.
"Sand, Sun and Songwriting! Girls trip of a lifetime! Goodbye paradise! Until next time.... #girlfriends ❤️"
Singer RaeLynn -- who has been on tour with Miranda over the past year, after Blake memorably mentored her on The Voice -- has also expressed her admiration for the beloved country star. The two even have matching tattoos, and Miranda turned to the 21-year-old for support the week after the divorce. "Thank you Jesus for girlfriends and coffee," Miranda wrote on Instagram at the time.

"The coolest thing about her is just learning from her," RaeLynn told ET in February. "One thing that I love about her is she takes time with her fans on stage. It's almost like going to school every day because every day I learn something new from her."
"Every song that she sings, it's a different emotion," she gushed. "She just has her fans in the palm of her hands, and I think that's a really special gift to have. I want to have that gift."

And it wasn't all gloom for Miranda on Wednesday -- she walked away with the trophy for Female Artist of the Year. "I needed a bright spot this year," she admitted in her acceptance speech.
She also showed off some of her signature sassiness on the red carpet. The svelte country star agreed that her sexy black Versace dress was a "revenge" dress when she was complimented on it.
"Her stylist said, 'See! It is your revenge dress,' and Miranda responded, 'Absolutely!'" our eyewitness observed.
