Sienna Miller 'wants to marry' Getty

Sienna Miller is already making plans to marry her latest boyfriend Balthazar Getty, according to a report today.

The actress is said to be thrilled after the billionaire oil heir spoke publicly about his plans to divorce wife Rosetta this week.

Miller has been accused of being responsible for Balthazar's marriage split. Meanwhile, Rosetta has reportedly been left "humiliated" after the couple decided to go public with their romance earlier this month.

A source told the News of the World: "Sienna is crazy about Balthazar. She knew that she would get absolutely hammered by everyone when their affair came out. That's why she was so desperate to keep it secret.

"Now that it's all out in the open, she's keen to settle down. She's really hoping he will divorce quickly and marry her."

Miller has announced that she is suing two British newspapers and a picture agency for publishing pictures of her kissing Getty. She has claimed that the snaps breached her privacy.
