Lady Gaga's headpiece contained almost 50,000 Swarovski crystals.
The 30-year-old singer songwriter - who performed during this year's annual Victoria's Secret Fashion Show, which took place in the Grand Palais in Paris, France, on Wednesday (30.11.16) - adorned five showstopping garments, but the black cowboy-style hat with beaded detail was emblazoned with 47,000 gems.
According to WWD, the 'Bad Romance' hitmaker recruited the American hat shop Gladys Tamez Millinery and a team of 10 people to create the statement accessory, which took the creative masterminds 300 hours to make.
However, this wasn't the first time the blonde beauty wore a garment from the store, as last month she adorned a white tailored suit, which she paired with a matching hat for the American Music Awards.
Gaga had a number of costume changes during the show, including a sequinned jumpsuit, worn with and without sleeves, as well as teamed with a white leather jacket, and a black and red long dress, which was teamed with her very own angel wings, but has hinted her finale ensemble was the most raunchy.
The musician, who donned a stunning Azzedine Alaia sheer lace crop top and trousers set at the end of the lingerie show, has admitted her last outfit made her feel like an "affair".
Alongside a photo of her on Instagram wearing the garment, she wrote: "A dress by @azzedinealaiaofficial worn for #vsfashionshow. Exquisite this piece, an affair really. Feels amazing in the City of Love in a dress made with so much of it.(sic)"
The designer also created the gown she wore on the Pink Carpet ahead of the show, and Gaga was very grateful for his support.
Alongside another image, she wrote: "Thank Monsieur ALAIA @azzedinealaiaofficial for my perfect Pink Carpet #vsfashionshow and Finale dress! I will always be grateful for not only your talent and generosity, but your simply stunning heart. there's only one ALAIA (sic)"
