London, Nov 3 : If rumours are to be believed, Sienna Miller's relationship with married American actor Balthazar Getty is on the rocks.
According to pals, Balthazar is stalling on his divorce to his wife Rosetta Millington, which is getting right up Miller's nose.
And he is refusing to move with the actress to London because he wants to remain close to the three sons he has with Rosetta.
"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," the Mirror quoted a pal, as saying.
"As well as the divorce, they are bickering over where in the world they are going to live and Sienna's love of partying.
"She's only 26 and loves to go out. But Balt is a former drug and alcohol addict who is now teetotal. It's tough trying to get a balance," the pal added.
Millare has told Getty she is not prepared to quit London for the States just to play the second wife.
The actress has already enlisted the help of an estate agent to find her a new London home.
