Alfie Allen and Jaime Winstone split?

Alfie Allen and Jaime Winstone have reportedly ended their relationship.

The couple began dating three years ago but have now told friends that they have broken up, the Daily Mail reports.

One source claimed that although the couple blamed work commitments for the split, the "spark" had gone from the romance.

"They've told friends it's down to conflicting work schedules, but it's really because their eyes have been wandering and the spark has gone," the insider said.

"Jaime says it's over this time."
