The actress got engaged last year to her hairdresser boyfriend and the couple have begun to make arrangements for their nuptials.
The soap star candidly opened up on her dream wedding dress, and revealed how she’s been managing her nerves ahead of the big day.
Speaking exclusively to OK! Magazine, Lacey revealed: “I’ve put on a few pounds since I bought my wedding dress, it’s so tight and they can’t let it out!
“What I’ve done now is I’ve eaten all the chocolate in the house so there’s no more to be tempted by until my wedding.
“I do feel more comfortable now, but I bought the dress when I was smaller. My best friend told me to get it in the bigger size, but the woman I bought it from said she’d never known a bride to put on weight before her wedding – I must be the exception!
She continued: “I’m sure it will be fine – when the nerves kick in I’ll probably lose a few pounds!

The soap star also revealed her plans to honour her great grandmother by wearing her wedding band on the big day.
“I’ve got my great nan’s wedding ring, which is 108 years old. I was four when she passed away and she was the loveliest lady,” Lacey explained.
“I get a funny feeling when I put it on,” she added.
Lacey and Matt got engaged during a romantic trip to Venice last year.
Matt popped the question while on a gondola ride through the Italian city and later took to Instagram to share the exciting news.
