8. [lastfm link_type="artist_info"]Willow Smith[/lastfm] (10-years-old) $4 million
She whips her hair back and forth. A lot. Enough to earn her a cool $4 million more dollars than we’ve got in our pocket. Really, for a 10-year-old she basically has everything figured out. We cannot wait for her to step out and emerge as the new Rihanna.
