However, it seems that the two ladies have very different approaches when it comes to raising awareness.
Lucy hosted a Macmillan coffee morning in Essex earlier today dressed in an elegant cupcake gown to match the occasion.
She was joined by her fiancé Mario Falcone at the event which was part of a nationwide coffee morning to raise money for people affected by cancer.
Talking at the event, the TOWIE star said: "I am really delighted to launch the World's Biggest Coffee Morning for such an amazing charity as Macmillan Cancer Support, and I had so much fun modelling this Cupcake Gown!"
Meanwhile, promotional pictures of Lucy's fellow TOWIE cast member Sam Faiers were also released today.
The blonde was supporting charity Breast Cancer Campaign's 'Wear it Pink' fundraiser- and from the looks of it got more than into the spirit of things.

Not afraid to make herself look a little silly, Sam dressed up superhero style, wearing a tight pink spandex suit as she emerged from a red telephone box.
Talking about her involvement, Sam said: "I'm delighted to be supporting 'wear it pink'."
"It's so important we find a cure for breast cancer and money raised at 'wear it pink' events will help Breast Cancer Campaign to fund the research needed to make this possible."
Lucy and Sam will be back on our screens when the seventh series of 'The Only Way is Essex' returns this Sunday at 10pm on ITV2.
