Sienna Miller is in a messy love triangle with a married millionaire a month after dumping actor Rhys Ifans.

The star has fallen for Balthazar Getty, 33, a member of the super rich oil dynasty.

But he is married with four children, including June Catherine, who is just eight months old.

His furious wife Rosetta Getty is speaking to divorce lawyers today.

It is not yet known if Sienna, 26, will be named in any court papers.

But it is another messy chapter in a tangled love life which has involved film stars Daniel Craig, 39, Jude Law, 35, and Ifans, 40.
