Carey: I didn't know concert was for Gaddafi family

Mariah Carey says she was unaware that she was booked to perform a concert linked to Gaddafi's clan - and she is embarrassed about it.

Carey is among a handful of entertainers paid handsome fees to give exclusive private concerts. It was later revealed the people behind those concerts were the family of embattled Libyan leader Muammar Gaddafi.
