New Mom Beyonce Shows Off Tiny Waist in Curve-Hugging Blue Dress


It's hard to believe that Beyonce Knowles was in labor just 10 weeks ago.

The "Naughty Girl" singer, 30, showed off her svelte post-baby body while heading into The Greenwich Hotel in New York City Monday. The new mom looked stunning wearing a curve-hugging navy blue dress by Victoria Beckham. Knowles accessorized with Nicholas Kirkwood platform heels, a gunmetal-gray clutch and two necklaces.

Once inside, Knowles attended a fundraiser dinner hosted by First Lady Michelle Obama, 48.

The 16-time Grammy Award winner, who welcomed daughter Blue Ivy with husband Jay-Z on January 7, will make her return to the stage over Memorial Day weekend in Atlantic City, New Jersey at Revel Beach's Ovation Hall.

Tickets for Knowles' three concerts -- scheduled for May 25, 26 and 27 -- will go on sale Friday, April 6 at 10 a.m. EST at all Ticketmaster locations, on and by calling 1-800-745-3000.
