Sienna Miller 'focused on Hollywood'

Sienna Miller reportedly wants to focus on her Hollywood career in the wake of her breakup.

The 33-year-old actress split from fiancé Tom Sturridge earlier this month, who she had been dating since 2011 and has three-year-old daughter Marlowe with.

Sienna's love life has made headlines in the past, such as her ex Jude Law cheating on her and her affair with married actor Balthazar Getty in 2008. Now she's single she's ready to focus on acting, according to an insider.

"Sienna felt her career hit a road block after the affair scandal and she lost a lot of potential work over the controversy," they told British magazine Closer. "She feels in recent years she's been getting much better roles in Hollywood and wants to make that her focus now."

With parts in hit flicks including Foxcatcher and American Sniper, Sienna's star is on the rise again.

In terms of her relationship with 29-year-old Tom ending, it's thought the four-year age gap between them played a part. Sienna apparently felt as though she was in a different place in life from her actor beau, with the source adding the spark eventually went out between them.

Tom is said to have tried to salvage their engagement though, but Sienna had other priorities.

"She told friends her romance with Tom was a huge whirlwind and, while she had once loved him, realised her feelings had changed," the insider said. "Tom was keen for them to set a date for their wedding and wanted to give the romance one more chance, but she told him that besides their daughter, her career was now her priority."
