British actress Emily Blunt has split up with her singer boyfriend.

The 25-year-old and Michael Bublé, 32, have ended their relationship after three years together, it was announced today.

Bublé's spokeswoman Liz Rosenberg confirms: 'They are no longer a couple.'

Blunt and Bublé met in 2005 when the actress, a huge fan of the Canadian singer, went backstage at one of his concerts to introduce herself.

They shared a home in Vancouver and it is thought the pressures of being kept apart by their busy schedules are the reason for the separation.

The news comes just three weeks after Blunt's The Devil Wears Prada co-star Anne Hathaway split up with her long-term boyfriend Raffaello Follieri.

As exclusively revealed by Mail Online, the 25-year-old movie star ended her four year relationship with the Italian-American businessman, 29, following more than a year of scandal linked to Follieri.

Just a week before their split, it was reported his charity Follieri Foundation, which funded vaccination programmes in developing countries, was being investigated by the New York State Attorney General's Office.
