Emma Stone and Andrew Garfield are ''finished''.

The couple were reported to have taken a break from their three-year relationship earlier this month but insiders insist the 'Birdman' actress has called time on the romance for good.

A source told Us Weekly magazine: ''[Emma] ended things and moved back to LA. It's finished. It's not just a break.''

One reason for the couple's split is said to be the 31-year-old actor's dedication to his role as a 17th century Jesuit in 'Silence', for which he has lost 40lbs and began shooting in Taiwan in January.

Another source said: ''He'd been in a dark place for months, getting into his role. He wasn't being the best partner.''

While the 26-year-old actress is said to understand Andrew's ''work anxieties'', it was previously revealed the pair's dedication to their respective careers was partly responsible for the problems in their relationship.

A source said recently: ''Emma understands his work anxieties - it's why she originally pulled out of 'Cabaret' last year and only did it this year - but they're taking a break from seeing each other.

''They're both a slave to their schedules. This time last year they were privately discussing marriage.''
