Sienna Miller and Balthazar Getty on the Rocks?

Not that we didn't see this one coming or anything, but apparently Sienna Miller's relationship with Balthazar Getty is on the rocks.

The couple is reportedly taking a "break" because Sienna is annoyed by his lack of commitment to the relationship. Well duh!

A source tells Britain's Mail, "Sienna is back in London to give them both some cooling-off time. They are still together at the moment but she has said things aren't good. There have been some pretty unpleasant rows, largely over Balthazar's reluctance to commit.

"She has really wanted to be able to step out as a couple but Balthazar is very torn over his children and it looks like he might be wanting to go back to his family. Sienna is devastated... Sienna is totally paranoid he is going to go back to his family. She feels very let down by Balthazar."

She's actually surprised that someone who left his wife and kids to have an affair has commitment issues? Come on, Sienna! You know better than that!
