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.

Her legs were mostly obscured by her dress, but she covered them up in a pair of fishnet stockings.

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.
