Hollyoaks‘ Jennifer Metcalfe has revealed she suffered pain and exhaustion filming the dramatic trailer for Mercedes and Riley’s wedding.

Pregnant Mercedes is set to marry footballer Riley Costello next week, but her dark secret – her affair with his dad Carl – could be revealed on the wedding day.

In the build up, Hollyoaks created an ominous black-themed wedding clip, for which Jennifer had to don a black dress and veil and cry a black tear.

Jennifer told Heat magazine: “It hurt. I have such sensitive eyes. I had my eyelashes dyed at the weekend, and even that was like the world was ending! You should have seen me. I’m just soft!”

But Jennifer revealed the cast managed to enjoy themselves filming the trailer.

She said: “To be honest it was a long day for us. I’m used to doing 12 or 13 hour days on set, but this took 15 hours. It was one, big, heavy day. But we got so much out of it and it got us out of the office, so to speak – so it was all fun!

“I think everyone got into the theme and feel of it. There were some right funny hairdos and stuff going on too, and people behaving really out of character. Outside of acting we all had a right laugh about it all, but at the time we all managed to hold it together and be totally serious.”

Whether Mercedes and Riley actually get married or if her secret is revealed is being kept strictly under wraps. But Jennifer revealed she has a big ‘dark’ storyline coming up.

She said: “It’s something that’s never been explored before with my character. It’s been intense and hard work, but I’ve loved every minute of it – I love seeing what my character’s going to get up to.”
