Gwen Stefani caught all eyes with her decollete in a mini-dress supporting Blake Shelton at ACM

The star-struck celebrity couple, Blake Shelton and Gwen Stefani, turned heads when they arrived at the 53rd Annual Academy of Country Music Awards.

The event, which took place on Sunday, April 15, 2018, was hosted by veteran country star Reba McEntire and paid tribute the best and brightest on the country music scene.

As reported by Daily Mail, the 48-year-old No Doubt singer, Gwen Stefani, wore a red mini dress featuring a neckline that plunged to her waist.

Her blonde hair was straightened, and she wore smoldering makeup. Stefani paired the outfit with fishnet stockings and thigh-high black boots.

Shelton also dedicated a song to her, and Stefani was clearly smitten as she sang alone from her seat. According to People, she jumped from her chair to give him a standing ovation.

Miranda Lambert, Shelton's ex, won the award for Female Vocalist of the Year, as well as Song of the Year for her track, Tin Man.

The song deals with her divorce from Shelton. In a somewhat awkward moment for Shelton and Stefani, Lambert thanked her fans for 'sharing [her] broken heart.'

The couple divorced in 2015, the same year Stefani divorced from her husband, Gavin Rossdale. Stefani and Shelton met soon after on the set of The Voice.

They announced their relationship in November 2015 and had gone from strength to strength since then. Shelton also accepted Stefani's three sons as his own.

Shelton doesn't have any biological children of his own, and the couple tried to conceive during 2017. Despite their efforts, Stefani couldn't fall pregnant, and those plans are on the backburner for now.

The ACM marked the end of a busy weekend for the star couple. Gwen Stefani attended a Sin City event on Friday, and Blake Shelton was rehearsing for the awards ceremony.
