Pete Wentz And Clay Aiken – Hasn’t The World Suffered Enough?

All kidding aside, musicians Pete Wentz and Clay Aiken have lent their voices to PSAs to boost aid for flood-ravaged Pakistan.

Both stars are ambassadors for UNICEF and their spots encourage people to donate money for the four million displaced children who are in need of water, medicine and shelter.

Scottish actor Ewan McGregor has also filmed a video calling on his fellow Brits to donate cash to UNICEF’s appeal.

More than 1,500 people have been killed and many more have been left stranded after monsoon rains caused the worst flooding in Pakistan for a century.

Meanwhile, back in La-La-Wood, Pete was seen with wife Ashlee Simpson and their son Bronx  leaving a friends house after a birthday party over the weekend!
