She may have given birth just a few months ago, but Beyonce is already back to her stunning pre-baby physique!

The busy new mom tore herself away from baby Blue Ivy for a few hours to attend a fancy fundraising event hosted by First Lady Michelle Obama, at the Greenwich Hotel in Manhattan, on Monday night, but Baby Blue wasn't far from her mom's heart!

Queen B chose a blue-inspired ensemble for the outing, wearing a navy blue figure-hugging dress by Victoria Beckham, paired with some serious bright blue bling and blue stilettos -- even her fingernail polish was blue!

President Obama was unable to attend the night's festivities which cost the attendees upwards of $2,000 a head, but First Lady Michelle Obama was there to take over the hosting duties, and she looked understated-chic in a green jacket and black bellbottom pants. Robert De Niro and his wife, Grace Hightower also attended the fundraiser, which will donate all proceeds to Obama's re-election campaign.
