Though his usual blonde companion is on-off girlfriend Chelsy Davy, the red headed prince was spotted cosying up to the Oscar winning actress at the Ascot polo grounds, reported Daily Mail online.
Though Theron at 35
is nine years older than the prince, the duo only had eyes for each other.
The young royal and the actress have a lot in common, especially their charity work in her native South Africa. Harry helped establish Sentebale, in Lesotho, in southern Africa to help orphans and the forgotten victims of poverty and AIDS.
Theron has established her own outreach project to help prevent the spread of HIV among teenagers in Africa.
