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 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."
