Britney Spears Is Working Hard, Looking Sophisticated In New Twitter Photo

Remember when Britney Spears was not a girl, not yet a woman?

Well she has definitely grown up since then. The "Work B*tch" singer posted an elegant and sophisticated photograph of herself on Twitter, showing the 32-year-old pop star in a much less glitzy light than we're used to seeing.

Despite the fact that her latest album, "Britney Jean" was released in late November and her "Perfume" music video debuted earlier this month, Spears is not slowing down or taking any breaks. It looks like she's brainstorming for her next project the old-fashioned way, with a pen and paper.

This Sunday, E! will debut Britney's two-hour special documentary, "I Am Britney Jean."
