The late singer's parents, Mitch and Janis Winehouse, hosted the Amy Winehouse Foundation's third annual benefit, which raises funds for the charitable organisation set up in the star's memory following her death in July, 2011.
The Winehouse family was joined by celebrities including Lott, Hall, actress Barbara Windsor and JLS star Oritse Williams, who all had kind words to say about the tragic Back To Black hitmaker.
Williams said, "Amy was one of my biggest musical inspirations. I studied her albums when I was a kid so I had to be here."
Hall added, "She was so talented. What a loss," while Lott said, "I love anyone who's got a soulful, amazing voice and she definitely had that. My favourite song was Love is a Losing Game because of the amount of soul that's in it."
