The `Am I Forgiven` singer - whose real name is Sarah Joyce - admits she annoys her management with her constant questions, but knows in reality she doesn`t require much attention from them.
She said: "My label think I`m a nightmare, because I`m constantly on their case about things.
"The good thing is that I`m low maintenance. I did my own A and R myself. And every album I make will work out of the box."
However the 31 year old beauty also reveals she was turned down by many record companies before label Atlantic picked her up, which she believes is down to her looks.
She reveals: "Other labels didn`t think I`m pretty enough. Well, you know, `You`re too fat.- "
Rumer also jokes she hasn`t listened to her album `Seasons Of My Soul` in its entirety since it was completed, but she is glad to finally be noticed by being nominated for awards, having been nominated for Best British Female at the BRITs this year.
She said: "I haven`t heard `Seasons Of My Soul` since it was mastered. But with the nominations there`s no feeling of arrival. It-s not that, but it is just to be recognised for doing something well, which is good."
