The talent was out at the Gala screening of new animated movie "Mr. Peabody & Sherman".
Joining the likes of comedian Bill Bailey and Britain's Got Talent winners Ashley and Pudsey was Peter Andre.
The Australian's song "Kid" is the UK's official track for the film, and he said it made him think of his son.
SOUNDBITE Singer, Peter Andre, saying (English):
"They wanted me to come and see the film and they asked me what I thought of the film afterwards and I said the relationship between Mr. Peabody and Sherman is the relationship between me and Junior, and they said can you write a song about it, and that was it."
The film tells the story of a genius dog, Mr. Peabody, who adopts and raises a young boy called Sherman.
After inventing a time travelling machine, the pair visit some of history's most famous moments, including ancient Egypt and the French Revolution.
British actress Leila Birch voices the machine.
