The 46-year-old wants to have more friends and family there on their special day and thought it would be better to move the date.
She revealed that the two aren’t actually engaged yet but have been “preparing to get married”.
“We’re both getting back to work now with everything opening up and it’s just finding the time, as we want it to be a big day and that takes a lot of planning,” she explained.
“We don’t want a small wedding. We want a big group of people and a big party with no restrictions.”
The star added to The Sun : “Plus, with all the weddings that have been cancelled because of the pandemic, there’s going to be a massive backlog and I wouldn’t want to get in the way of all of them. Let them all go first!”

“Eddie will be surprised watching this but all of that got cancelled. I was planning to and then we had conversations again last year and we said we would like to get married.”
Denise was previously married to West End and Casualty star Lee Mead but after four years of marriage, they split in 2013. They share a nine-year-old daughter, Betsy.
Speaking about how thoughts of marriage came about with Eddie, Denise said: “I said, ‘Let’s not worry about getting engaged. We’ll just plan a day and have close friends and family there when things reopen’.”
She added that because “we’re like a married couple anyway”, they thought that marriage would be a good way to show their feelings for each other.
