Rashida Jones - Jones Planning Six Month Music Study

The Social Network star is waiting until she has a long period off from making movies so she can "devote" herself to singing.

She tells U.S. talk show host Piers Morgan, "It's something that I love to do. But I feel so strongly that I want to be so good at it, and I want to know music in and out. And I want to know theory.

"I want to lock myself in a room for six months and just know it - you know, know music in and out, and feel comfortable with it. But unless I could devote my soul to it, I wouldn't want to do it, because I would want to make him proud."
