Lily James is afraid she will "burn out".
The 'Cinderella' star - who also plays Lady Rose in the popular drama 'Downton Abbey' - has been busy in 2015 on various acting projects and is in need of a well earned "long chunk" of holiday to ensure she doesn't suffer from exhaustion next year.
Lily shared: "I'm actually taking Christmas off. I haven't had a really long chunk of time in a really long time. I don't want to burn out. I want to regroup and have just a bit of time to myself before going to New Orleans in February for 'Baby Driver'."
In 'Baby Driver' the 26-year-old star plays an American waitress who loves to sing.
Despite being good at it herself, Lily confessed she has lost her confidence and will be putting some practice in ahead of filming.
She told The Sunday Times Magazine: "She's a real dude. She's always singing.
"I'm going to Nashville with a girlfriend. I might go to open-mike events. I love singing, but I've lost my confidence becase I haven't done it in a while."
