Fans react to Gwen Stefani's racy red mini-dress during her appearance at the ACM Awards

Miranda Lambert might have been crowned as Female Vocalist of the Year at the ACM Awards, but it was Gwen Stefani who stole the show.

The 48-year-old No Doubt singer and mother-of-three wore a red mini dress featuring a neckline that plunged to her waist. She paired the outfit with fishnet stockings and thigh-high black boots.

As reported by Pop Culture, Stefani completed the look with a ring on each finger, a sparkly clutch, and smoldering eye make up while choosing a nude color for her lips.

Her blonde hair was straightened to cascade over her shoulders, and her outfit quickly took social media platforms by storm as fans rushed to comment on her look.

A Tiffany Freud, a Twitter user, noted that 'Gwen Stefani in boots, fishnets, and a red dress is everything,' while Cindy remarked that Stefani's hair and makeup 'was perfection.'

A user known only as Yummyboy91 described the Just A Girl singer as an 'amazing queen.' Taline Knight congratulated Shelton for 'taking home the best award of the night, the gorgeous Gwen Stefani.'

Clearly a fan of the nude lip color, another Twitter user, Lindsay, said that while she loved Stefani's signature red lips and hair, she also adores it 'when she does something different.'

Some fans only focused on her lips. James warned her to go easy on the lip injections while Jessica Lee Hall remarked that Stefani's lips are bigger than Shelton's head.

Stefani had been dating Shelton since November 2015, soon after their respective divorces were finalized. Shelton was married to Miranda Lambert.

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 in November 2015 that they were a couple, and their relationship has gone from strength to strength since then.
