{blackbabes} Beyoncé stuns in body-con dress at Obama fundraiser

Having a live-in personal trainer certainly does wonders. Just two months after giving birth to daughter Blue Ivy Carter, Beyoncé's body already appears to be back in top shape.

Beyoncé arrived at a fundraising event for Michelle Obama in Manhattan yesterday wearing a body-hugging navy blue dress from designer Victoria Beckham. The slim-fitting dress showed off the songstress' toned stomach and hips, while a zipper in the back showed off her shapely rear.

According to Star magazine, Beyoncé has had trainer Marco Borges living with her to guide her through two-a-day workouts at both 5am and 5pm. A source told the magazine that the singer has been "living on protein shakes, egg-white omelettes, pineapple chunks and lots of ice-cold water" in a bid to lose 40 pounds and "have a better body than ever."

At the Obama fundraiser, Beyoncé also notably stuck to her favorite hue with a navy blue dress, turquoise nails, and dark blue shoes, perhaps in a visual nod to daughter Blue Ivy.
