Sienna Miller and Balthazar Getty Split

The honeymoon period is definitely over for Sienna and her oil heir love

The controversial romance between Sienna Miller and married dad of 4, Balthazar Getty, looks to be over.

Rumours of a split have dogged the pair since they were first pictured together in the summer, with many reporting Getty had returned to his wife and children.

Now it appears the strain was too much for the couple, with Sienna openly admitting she is single and cool with being "on my own."

She told Usmagazine.com: "I'm single at the moment, and I'm completely happy with that. It's nice not to have a relationship that the press constantly want to scrutinise and discuss."

The couple are thought to have split after a series of disagreements over where to settle down and about Siennas party lifestyle.
