• Lady Gaga debuted her latest Haus Labs line, Casa Gaga Italian Glam Collection, at the premiere of House of Gucci.

• Haus Labs products were also used in the film itself.

We're still thinking about Lady Gaga's glam at the UK premiere of House of Gucci on 9 Nov. The star, who plays Patrizia Reggiani in the upcoming film, stole the red carpet. As it turns out, she used products from her own brand, Haus Labs, and debuted her latest Casa Gaga Italian Glam Collection right before our eyes.

The makeup for the London premiere was inspired by Patrizia herself, which Lady Gaga's makeup artist Sara Tanno described as "bold and powerful" in an Instagram caption detailing the full product breakdown. Tanno used the new Tutti Gel-Powder All Over Rouge (£30) in "Rossini" and "Bellini" on Lady Gaga's cheeks and the golden, glowy Tutti Gel-Powder Highlighter (£39) in "Luca Del Sol" to add radiant to her skin. "Her lips were a tribute to Patrizia tonight, lined dark but in Gaga's natural rounded shape instead of Patrizia's signature sharp-lined lips," said Tanno. She used the shade "Marcello" from the Tanti Baci Extreme Cream Mini Lipstick Set (£54) with the La Luce Lip Glaze (£24) in "Caramella D'oro" layered on top.

The Gucci-level glam Casa Gaga makeup collection was used in the movie itself, too. The limited-edition lineup stars at £19 (but goes up to £184 for the entire set) and has luxe gilded packaging that makes the products look like collector's items. Even the shades are aptly named after Italian stars, pastries, and cocktails. The entire collection is a love-letter to Italian culture — as Lady Gaga said in a press release: "There's glam, then there's Italian Glam."

"We wanted to do the makeup in a way that they would've done in that time so it felt authentic," Tanno said of the makeup looks in House of Gucci. "Something that was difficult to find with modern textures was the finish. All of the makeup back then had a velvet finish without a heavy pearl. It was really important to mimic these textures." That's where Haus Labs came in.

They created over 50 looks in the movie for Lady Gaga during her time as Patrizia. "We had to take her character from the '70s through the '90s," said Tanno. "There was [a] graduation of the type of makeup and the style, whether it was the shape of the eye or the lip."
