Jennifer Hudson is set to sing with the chorus from Sandy Hook Elementary School at the Super Bowl in the US.
The Grammy and Oscar-winning singer will join the chorus - which features 26 children from the school in Newtown, Connecticut, where 20 children and six adults were killed in a shooting rampage in December - to sing before the game.
Jennifer, whose mother, brother and nephew were murdered in 2008, will perform America The Beautiful with the group.
The performance will be part of CBS's pre-game show before the game between the San Francisco 49ers and the Baltimore Ravens, and will be broadcast live.
Alicia Keys will sing the national anthem.
