Hollyoaks star Jennifer Metcalfe has promised that viewers will be impressed by the drama surrounding her character's wedding day.

Mercedes prepares to tie the knot with Riley Costello (Rob Norbury) next week, but the wannabe WAG could have trouble ahead as she continues to harbour the secret that she cheated on the young footballer with his dad Carl (Paul Opacic).

Warren, Mitzeee, Seth, Jacqui and Doug are among the show regulars who know the truth, and all have their own reasons for wanting to reveal all. However, Hollyoaks bosses are currently keeping tight-lipped over exactly what happens at the ceremony.

Metcalfe told All About Soap of the storyline: "There are six or seven people who know the whole truth and any one of them could spill the beans at any time. She's really walking on eggshells - she loves Riley and wants to marry him."

She continued: "When the wedding day finally arrives, it definitely doesn't run smoothly at all. There are going to be huge repercussions from the day - in fact, my next few months of storylines all stem from the wedding.

"I can't say too much, but it's about to get even more exciting. The writers have definitely come up with the goods."

Hollyoaks airs its WAG wedding on Monday, October 17 at 6.30pm on Channel 4.

Spoiler:

It looks like Mercedes won't be killed by Silas then, unless he just tries to scare her.
