The 22-year-old actress plays Snow White in new movie `Mirror, Mirror` and says the role was a dream come true because she loved fairytale films when she was younger.
Lily - the daughter of singer Phil Collins and his second wife Jill Tavelman - said: "My mum and dad used to read me fairytales every night before bed. I was probably the annoying child who would press `replay` on every single Disney fairytale; my parents know all the words because I couldn`t get enough! I definitely grew up obsessed!"
Lily says Snow White was always her favourite princess because she could relate to her the most.
She told The Guardian`s Film3sixty magazine: "All fairytale princesses have their own story arc, but for me, Snow White was the one that was most about a young girl growing into her own. Every little girl and their mother and their grandmother have a little bit of Snow in them.
"And I think it was fun to be able to tap into a more modern-day version that young girls could relate to, and which would also give adults a chance to revisit that little princess within them, to put everything else aside and become a little girl again."
Melanie C would like more children.
The former Spice Girls singer already has three-year-old daughter Scarlet with partner Thomas Starr and she says it would be a dream come true of she could have another baby.
The 38-year-old star exclusively told BANG Showbiz: "I`d love to have more! I definitely like to have at least one more but yeah you never know what life holds so that`s something I`m hoping for in the future."
The `I Turn To You` hitmaker says she loves everything about being a mother but does find it hard to strike the right balance between working and looking after Scarlet.
She said: "I think because of the times we live in there`s so much to do you know and whether you know like myself- my work is kind of different hours and I travel or even whether you work a regular working week or even if you`re a stay at home mum there`s just so much in everybody`s life`s so yeah it`s hard to get that balance and we`re all just working at it aren`t we trying to make it work."
Melanie also says that while she`s very happy with Thomas - who she`s been with for 10 years - she has no plans to marry him.
When asked if she had any marriage plans, she said: "Nope, no change there. We`re very happy the way that we are. We have talked about it but we`re cool, we`re happy where we are."
