Baby Blue Ivy entered the world just ten short weeks ago, but we would have never guessed judging by Beyonce’s fit figure!

The new mommy stepped out in a form-fitting navy dress, designed by Victoria Beckham, in Manhattan Monday night to go to dinner at the Greenwich Hotel with First Lady Michelle Obama for a fundraising event.

Beyonce was joined by her mother at the event, and the guest list included some other famous figures such as Robert DiNero and Ben Stiller.

The point is, Beyonce is looking mighty fine for just having a baby! She could make a killing off of a book about how to get rid of baby weight.
