It was only last week that she announced her new beauty line Haus Laboratories.
On Wednesday, Lady Gaga arrived at a party in West Hollywood celebrating the cosmetics line.
The 33-year-old actress and pop superstar showed off her edgy fashion sense with her all-black outfit.
Gaga was decked out in a black leather dress that highlighted her curvy figure.
The strap-free outfit showcased her bust and was adorned with a gleaming jeweled strap over one shoulder.
The 5ft1in beauty elevated her stature with a pair of her trademark black platform boots.
Her legs were mostly obscured by her dress, but she covered them up in a pair of fishnet stockings.
The Star Is Born actress carried along a coat covered in wispy black feathers.
Her peroxide blonde locks were styled up in a classic ’60s-style beehive, with her bangs swept to the side.
She kept things off-kilter, wearing a studded earring on one side and long irregular strands of diamonds on the other side.
On Monday, Gaga shared a celebratory photo of herself in a white graphic T-shirt with the same black feathered jacket.
She had a black Haus fanny pack and led a champagne toast for the new brand.
‘The last thing the world needs is a new beauty brand…but that’s too bad,’ said the Poker Face singer on Tuesday in an Instagram video announcing the line.
The rave-like video featured a diverse array of models with bold eyeliner and glittering makeup.
‘They say beauty is in the eye of the beholder, but at Haus laboratories, we say beauty is how you see yourself. Your glam, your expression, your artistry. We want you to love yourself,’ she continued.
The clip concluded with the oddly combative line: ‘Haus Laboratories. Battle for your life.’
Earlier on Wednesday, Gaga shared two photos of herself in an irregularly shaped cheetah print blouse.
She tagged @hauslabs and blew a kiss for the camera while showing off her cool with a pair of aviator sunglasses.
