Sienna rubbishes dating rumours

Sienna Miller finds suggestions she dumped Jude Law for a co-star "laughable".

The 29-year-old actress – who called time on her 13-month relationship with the ‘Alfie’ star in January – insists the split was "amicable and mutual", and slammed recent rumours she is dating Joe Armstrong, who she stars with in London stage production ‘Flare Path’, as "ridiculous".
