Beyoncé glittered on stage in a puffy-sleeved creation at the Country Music Awards in Nashville.
The dress is made by Melbourne designers Jacob Luppino and Anthony Pittorino, the duo behind J'Aton Couture.
Beyoncé performed two songs with the Dixie Chicks on Wednesday night while wearing the sheer gown.
Rebecca Judd posted an excited Instagram post to celebrate the Queen Bee wearing one of her favourite labels, captioning it: "Beyoncé performing in @jatoncouture at the CMA's today. No biggie Freakin killing it boys!!!!! Cannot wait to launch our #jatonxjaggad range next week!
J'Aton also famously designed Bec Judd's Logies maternity look earlier this year.
And blogger Nadia Bartel wore a J'Aton jumpsuit to the Brownlows a few weeks ago.
