It comes after last-minute preparations were made to the outside of the church this morning as rainy conditions threatened to put a dampener on the day.

Stunning hydrangeas and roses in pretty pastels and greens lined the walls of the venue as raincoat-clad staff made sure everything looked as it should.
Guests are expected to start arriving for the wedding at midday, followed by Anne-Marie at 12.45pm ahead of the service which began at 1pm.

It comes after insiders told The Sun: ‘Neither of them want the razzmatazz of a showbiz wedding’, and insisted the day will be ‘simple and beautiful’.
