To be honest, I feel really quite sorry for Sienna. Nobody can know for sure if it really was her who broke Balthazar and Rosetta up or if they were seperated before already and now she's the one who gets blamed and insulted. And personally, I don't buy Rosetta's publicity..
Yeah exactly. Rosetta doesn't have to come out and say anything because she's got her PR and friends planting stories left right and center. Even if, her and Balthy were still together when he got together with Sienna, we have no idea what he told Sienna and regardless, Sienna could have tried all she wanted to get together with him, if he wasn't interested, they wouldn't have gotten together.
I honestly don't see much of a difference. Fact: Balthazar and Rosetta were together on April 23rd. It's awfully close that he and Sienna are now running around showing of their new relationship. Bad taste IMO.
To be honest, I think Sienna loves being in the tabs; she has even been seen buying one. She's certainly not known for her acting so I suspect she's usually quite happy with the attention. Also - if she doesn't want the paps to follow her now, maybe she should stop being where the paps are. IMO 
, nor parade around with Balthazar publicly (as seen in the shopping pics). That's just asking for it IMO.
We always jump on the woman.
