Game of Thrones star Alfie Allen and actress Jaime Winstone have split up due to their busy work schedules.

27-year-old Alfie - the younger brother of Lily Allen - is busy filming Game of Thrones' season five in Belfast while Jaime has to stay in London for work commitments. 

The pair called off their engagement in 2010 before reuniting last year. According to the Daily Mirror, friends of the couple are shocked and they believed the engagement would be back on. 

Last year, Jaime said: "I'm really happy. He's my best friend."
