Aubrey O'Day's bod is a real show stopper.

The Danity Kane singer showed off her recent weight loss this morning on Instagram, posting a photo of her very impressive physique in a black bikini.

"I love the way bitches look at me," she wrote along with the pic -- referencing one of her pink-haired pooches in the background. FYI: The photo on the left was taken in 2011.

The 29-year-old is gearing up for a DK reunion.

The girls (minus D. Woods) announced they have a new single, "Rage,"  coming out "soon" back in August -- and that they're working with the mastermind behind "Damaged."
