Boy, Balthazar’s fling with homewrecker Sienna Miller is costing him big time. Not only in the media, but wear it hurts most, in his pocket book. His family has sided with Rosetta and his four kids, by financially covering her expenses, and cutting him off. Sources report that she refuses to divorce her hubby as well.

According to TMZ:

We’re told Rosetta doesn’t want to declare the marriage over, which would allow him to separate future earnings from her. She’s the one raising their four kids and she feels she’s more financially secure if she doesn’t file for divorce.

And there’s one more big thing. We’re told the Getty family is so appalled at Balthazar’s affair with Sienna Miller, they are supporting her — in more ways than one. So why rock the boat?

I guess you can’t help who you love, but Sienna Miller has some serious issues dating married men. What does her astrological chart say? Sienna Miller was born December 28, 1981 and is a lusty Capricorn girl. She also has Moon and Mercury in Capricorn, squared by flirty Libra. She’s a fun loving party girl, who is ruled by her heart, versus her head. But watch out Getty, this chick gets bored easily. Her Venus in Aquarius makes her super friendly and someone who definitely needs her space.

I think Getty and Sienna have a strong soulmate connection but like most passionate relationships, they soon fizzle out. By next year, Sienna will move on to bigger fish. But remember, karma is a bitch, and she’s got Sienna on speed dial. Stay tuned.
