Watch out!

Kelly Ripa had some trouble with her sky-high stilettos while on the red carpet for the annual CNN Heroes: An All Star Tribute in New York City.

The talk-show host lost her balance and took a tumble while posing for photos. But fret not, the fall only last for a split second and Ripa walked away like a champ!

And while she may have recovered swiftly from the blind-and-you-missed-it moment, Allison Williams did rush to Ripa's side to lend a helping hand.

The Girls actress, who looked stunning in a leather L'Wren Scott dress, couldn't help but giggle as she assisted Ripa.
