The `All About Tonight` hitmaker does not like being on her own - despite being 21 - and when her boyfriend Oliver Cheshire can`t join her when she has to travel the world, she brings along her mother.
She said: "My boyfriend, Oliver, is a model and often just as busy as me, so mum still comes along when I travel. It`s no fun being in a hotel on your own - I get lonely. She looks after my scheduling because I`m rubbish at that. She`s also honest and tells me straight if I`m doing something wrong. She always has my best interests at heart."
Pixie is so concerned with what her mother thinks, she is not sure if she would even get a tattoo without her permission.
She said: "I`m just the same now as when I was a teenager. Drugs don`t interest me but I like to go out with my friends and have a good time. I`ve thought about having a tattoo, but I don`t think mum would like it."
