Lots of celebrities, including Nicole Richie, were spotted arriving at Jim Henson Studios in Hollywood to record "We Are the World", yesterday, February 1.
The song originally composed by Lionel, Nicole's dad, was re-recorded to raise money for Haiti earthquake relief.
Miss Richie twittered:
"I was 4 years old in a studio watching my dad record We Are The World, & today I get to do it again. Excited to help make a change."
