Report: Sienna Miller pregnant with Law's child

Sienna Miller is six weeks pregnant with estranged fiance Jude Law's child, according to an American magazine.

Star claims the couple told their parents the happy news just two days before revelations Law had an affair with his children's nanny emerged.

The pair split following the claims, and Law's admission he slept with Daisy Wright while filming movie 'All the king's men' in America last year - but they reportedly met in private in England for secret talks in a bid to rescue their relationship.

Miller has refused to comment on the pregnancy claims.
