The actress, who showcased her vocal talent in the movie Country Strong and TV musical Glee, said that she wants to make sure she does everything in the "right way".
She told Ellen DeGeneres: "Well, I haven't signed anything but I'm thinking about it. I kind of have to get my head around the concept of it and how I would want to do it. Do it in a right way.
"It's hard to think of switching because all the singing I've been doing has been coming out of Country Strong or Glee.
"So I think, how would I do that? Just a record by myself feels a little scary to me. I would like to in theory but we'll see."
She added: "I like all kinds of music. I don't think it would be a real poppy record. [Britney Spears has] cornered that market."
