John Legend and Idina Menzel for Super Bowl show

John Legend and Idina Menzel have signed up to kick off Super Bowl spectacular next month (Feb15).

The All of Me singer has agreed to sing America the Beautiful before the big football game starts at the University of Phoenix Stadium in Arizona, while Menzel will follow in the footsteps of stars including Whitney Houston and Christina Aguilera by singing National Anthem The Star-Spangled Banner.

The news comes just a day after Legend landed an Oscar nomination for his Selma song Glory, and Let It Go hitmaker Menzel reveals the gig is a dream come true, writing in a message posted on Twitter.com, "I am so humbled and honoured to be asked."

Katy Perry will provide the half-time entertainment at the big game, which takes place on 1 February (15).
