Sienna Miller and Tom Sturridge have split up. The showbiz couple has reportedly decided to separate, more than three years after they got engaged. The actress was spotted holidaying with the star earlier this month in Ibiza although the trip was not enough to save their relationship, according to The Sun newspaper. The news comes just two months after the 'American Sniper' star was seen without her engagement ring while at Cannes Film Festival prompting rumours their relationship could be on the rocks following what friends described as a series of "blazing rows". It's not the first time Sienna Miller has been unlucky in love, having broken off her engagement to Jude Law in 2006 after they both admitted they had been unfaithful.
