Aubrey O’Day doesn't hold back when it comes to, well, anything.

The singer may have put on some weight since her days in the girl group Danity Kane, but recently she's been showing off a much slimmer physique — and it looks like she's proud of it!

"I love the way bitches look at me," Aubrey wrote on Instagram along with pic of herself wearing a black bikini. The former Celebrity Apprentice star showed off another belly-baring pic a couple of months ago with the caption, "Aubrey's gettin her Groove back!!!! Thanks @barrysbootcamp!"

Barry's Bootcamp is self-proclaimed as "The Best Workout in the World," combining cardio and strength training in each class, and it seems to be working for Aubrey. Compared to a photo of her wearing a bathing suit in Las Vegas last summer (left), the TV personality definitely seems to be back on track.

What do you think of Aubrey's slim-down? Sound off in the comments!
