Sienna Miller's much talked about relationship with actor Balthazar Getty is reportedly in trouble.
The actress began dating the Brothers And Sisters star earlier this year but she is reportedly becoming increasingly frustrated with his reluctance to divorce his estranged wife.
A source told Female First, "They had such an animal attraction in the beginning. Now the dust has settled and they're talking about the future, there are a couple of things they have been rowing about.
"As well as the divorce, they are bickering over where they are going to live and Sienna's love of partying. She's only 26 and loves to go out. But Balthazar is a former drug and alcohol addict who is now teetotal. It's tough trying to get a balance."
