During the 37-year-old's fashion show, two 1-minute silences took place at 09:59am and 10:03am, marking the times the Twin Towers were hit on 11 September 10 years ago.
After the event, the former Spice Girl posted a picture on her Twitter page of the New York skyline, showing the beams of light to mark where the Twin Towers of the World Trade Center stood before the terrorist attacks.
Alongside the photo, Beckham wrote: 'The powerful & beautiful Tribute in Light in honour of all those who lost their lives, we remember you.'
