Justin Bieber, Lady Gaga and Michelle Obama are giving a helping hand to Beyonce.

Obama and the pop stars have signed on to support Beyonce and the global campaign for World Humanitarian Day on Sunday.

The campaign asks that on Sunday people help others through such acts as making sandwiches for the homeless or volunteering at a local charity. The goal is to share one billion messages of hope.

A representative for Beyonce says that Bieber, Gaga, Mrs Obama, Rihanna, Shakira, Jay-Z, Gwyneth Paltrow, Chris Martin and others will participate.

Beyonce performed her song I Was Here at the United Nations in New York last week to promote World Humanitarian Day.

The performance was taped and the music video will debut on Sunday. The song is from her latest album 4.
