Up for five awards, Lambert, 33, took the stage to perform her new track “Tin Man” before she was awarded the album of the year honors. When her name was called, the star leapt from her seat, receiving a hug from East, 28, before returning to the stage to accept her trophy.
“Thank you for letting me use my heartbreak and sharing it with me,” Lambert said in her speech, alluding to last year’s The Weight of These Wings, the first album she released after her 2015 divorce from Blake Shelton.
Later in the evening, Lambert made history, becoming the first ever performer to take home the female vocalist of the year title eight consecutive times.
“Thank you so much guys. It really means the world to me. Carrie can sing me under the table. We’ve agreed on that. I’m just glad to see females kicking ass these days. I’m so to be apart of that. So cheers to all of us girls out there dreaming,” she said in her speech, acknowledging her fellow nominees — Kelsea Ballerini, Maren Morris, Kacey Musgraves and Carrie Underwood — then gesturing at East in the front row before exiting the stage.
A year ago, Lambert and East made their romance red carpet official at the 2016 ACMs, just months after PEOPLE confirmed the pair was dating in December 2015.
The couple has remained fiercely private about their relationship. But last November — one day after attending the 50th Annual CMA Awards together — Lambert took to Instagram to slam social media trolls who left hateful comments about them online, defending her romance with “my sweet man.” East followed suit, sharing a photo with Lambert from the show, simply captioned: “I was the big winner last night!”
In addition to her ongoing My Highway Vagaond Tour, Lambert will hit the festival circuit this summer; East — who contributed a song, “What Would It Take,” to the Fifty Shades Darker soundtrack — will open for Chris Stapleton on tour this summer.
The ACM Awards broadcast live from T-Mobile Arena in Las Vegas on April 2 at 8:00 p.m. ET on CBS.
Dropping hints? Miranda Lambert shines bright in white while at ACM Awards with boyfriend Anderson East
They first met in September of 2015.
And on Sunday, Miranda Lambert, 33, made a dazzling arrival at the Academy of Country Music Awards at Toshiba Plaza in Las Vegas, Nevada.
The country songstress was joined by her boyfriend of over a year, singer Anderson East, 28.
For her big night, the country songstress was dripping in diamonds.
The pretty blonde wore a Hearts on Fire, tooth-like diamond necklace and detailed cuff. She also wore a collection of rings from the brand, as well as Djula and Harry Kotlar.
Her jewellery was complete with a pair of Borgioni spike earrings.
The Grammy award-winner dressed her slim figure in a sleeveless white gown with gold applique detailing which could have easily been a wedding gown.
Since December 2015, Miranda has been dating her younger musician beau, Anderson. The two first met at the Live on the Green Music Festival just three months before.
And now, it seems like the couple could walk down the aisle soon, a source revealed to E!.
'Miranda and Anderson are doing good. They try to keep their relationship private and out of the public's way. They are definitely gonna get married.'
'She has learned many things about what she wants and needs after her breakup and Anderson fulfills it all.'
The Miranda insider noted that the duo 'never argue' and are 'understanding with one another.'
'[They] have couple time and during that they always give back to the community and their charities. Miranda is happy and everything else is in perfect place between her heath, music and her love life.'
Prior to her relationship with Anderson, the beauty was married to Blake Shelton from May 2011 until July 2015.
During the AMCs, Miranda took the stage to perform her song, Tim Man, from her latest album, The Weight of These Wings, according to The Boot.
The Southern belle was styled in a sharp contrast from her wintry white look on the carpet, choosing a dark, long-sleeve mini-dress and platform heels.
Miranda was nominated for five awards in the show, including Female Vocalist of the Year and Song of the Year.
She has since won Album of the Year.
