The 24-year-old actress, who plays student Tilly Evans on the Channel 4 soap, has been dating her 22-year-old co-star (Callum Kane) for two years since they met on Hollyoaks.
"Until recently we hadn't actually been on set together! Laurie has completely separate storylines from me and, because he's part of a family, he mostly tends to do scenes with them," she told Inside Soap.
"But in Hollyoaks Later, we've been working together and it's been really good actually. I always worry that if we spend every hour in each other's company, we're going to get tired of it, but it just hasn't happened."
Lucy, who joined Hollyoaks in June 2011, said she would like to follow in the footsteps of Ashley Taylor Dawson, Ricky Whittle and Ali Bastian and shimmy onto the dancefloor of BBC show Strictly Come Dancing.
"I'd love to go on Strictly Come Dancing because my mum used to do the foxtrot, tango and ballet when she was little, and I think she'd love to say that I'd been on a TV show and done all that. And I really do love dancing - I used to do a lot of it when I was younger," she said.
