The married man accused of having an affair with Sienna Miller has denied reports he is romantically involved with the British actress. The Alfie star was rumoured to be dating actor Balthazar Getty following her split from boyfriend Rhys Ifans last month after the pair was photographed out and about in Los Angeles together last week (begs23Jun08). But Getty, who is married with four children, has refuted allegations he is involved with Miller, saying, "It's not true. No truth to any of that."
