Putting one foot in front of the other is easier said than done for Beyonce Knowles.

The singer, 29, wowed on the red carpet in a black Emilio Pucci gown with gold detailing at Monday's Costume Institute Gala Benefit, but when it came time to head inside New York City's Metropolitan Museum of Art, she got tripped up.

After briefly posing for photos with husband Jay-Z by her side, Beyonce headed into the party, but not before Jay-Z and a pal had to literally carry her up the steps to the venue.

Music's hottest twosome weren't the only power couple to hit the carpet at Monday's event honoring late designer Alexander McQueen.

Gisele Bundchen arrived on the arm of husband Tom Brady, while Orlando Bloom and Miranda Kerr and Josh Duhamel and Fergie made the annual event a black tie date night.
