Sienna Miller enjoyed secret dates with Balthazar Getty before splitting from Rhys Ifans?

The 'Factory Girl' star was introduced to the married millionaire by Matthew
Rhys - who stars with Getty in hit US TV show 'Brothers and Sisters' and is
Sienna's ex-boyfriend.
The pair reportedly enjoyed dinner together in Los Angeles while Sienna was
filming 'GI Joe' in March, but their romance only got serious when Sienna
dumped Rhys earlier this month.
A source revealed to Britain's The Sun newspaper: "Sienna has known
Balthazar for a while and they've spent more time together over the last
four months.
"They became closer after spending time dining with friends at the Chateau
Marmont in March and April.
"When Sienna realized she had feelings for Balthazar, she ended her
relationship with Rhys over the phone. She wanted to do the right thing
before things really happened between her and Balthazar. Since then things
have quickly got very intense between them."
A friend of Matthew - who was accused of causing Sienna and Rhys' split
after he got too close to his ex during filming of 'The Edge of Love' -
said: "This behavior is typical Sienna. At least Rhys Ifans can try to get
over it now."
Balthazar has four children with wife Rosetta.
Rosetta is reportedly furious about the allegations he is dating Sienna and
has called in divorce lawyers.
