The mum-of-one had lended her vocals to a very special project, and she looked flawless as she officially celebrated the single at The May Fair Hotel in London.
Former Mis-Teeq star Alesha features on the record, 'We are the Children United', along with the voices of thousands of children from across the globe.
The single has been launched by new children's charity Children United, bringing children together from across the globe and giving them the opportunity to have their voices heard.
Alesha said: "Getting involved with Children United was a no-brainer! I just thought the whole idea was fantastic. I love the idea of children coming together from all around the world – having a voice and being heard. I think it's really important. They're the next generation and we need to hear them and they need to be considered.
"I just think it's a fantastic charity," she continued. "One that I want to continue to support. I think that anything that involves music as well is such a fantastic way to connect to the hearts of people."
'We are the Children United' is available to download from iTunes now.
