Mariah Carey's new song will raise money for human rights issues.

The singer - who recently admitted she felt "horrible and embarrassed" about being paid $1 million to sing for the son of Libya's Colonel Gaddafi - plans to donate the proceeds from her new song 'Save the Day' to human rights causes and may even set up her own charitable foundation.

This is not the first time the pregnant pop star - who is expecting twins with her husband Nick Cannon - has donated money to charity, her singles 'Hero' and 'One Sweet Day' have generated millions for good causes.

Mariah released a statement yesterday (04.03.11) admitting her embarrassment at giving a private performance for family members of dictator Gaddafi - who has been linked to terrorist activity and accused of running a brutal regime over his people for 40 years - at a party in the Caribbean in 2006 and vowed to be careful about who she works for in future.

She said: "I was naive and unaware of who I was booked to perform for. I feel horrible and embarrassed to have participated in this mess.

"Ultimately we as artists are to be held accountable. Going forward, this is a lesson for all artists to learn from. We need to be more aware and take more responsibility regardless of who books our shows."
