Earlier this week, Beyonce Knowles, her mother Tina Knowles and her mother-in-law, Gloria Carter attended an event in support of President Obama’s re-election campaign at the Greenwich Hotel in New York City. Beyonce wore a blue Victoria Beckham dress and Nicholas Kirkwood heels. She later met with her husband for dinner in Tribeca.

Look how flat her tummy is. WOW @ her post baby body!

The cocktail reception and dinner, which was held at Locanda Verde restaurant at the Greenwich Hotel and cost $5,000 per person, was organized by First Lady Michelle Obama who didn’t fall behind in the style department. The first lady changed from a green trouser suit to a dazzling black and silver dress for the event.

Guests paid $5,000 for a photo with her while those who wanted to mingle with the First Lady forked over $25,000 for a ticket. Other attendees included Angela Bassett, Gayle King, Star Jones, and Whoopi Goldberg. Actor Robert De Niro and his wife, Grace Hightower, also hosted the 85-person event (held at their hotel) meant to raise money for the Obama Victory Fund.
