52 Million: Trey Smith (26)
Trey Smith is Will Smith's oldest child, born to his ex-wife, Sheree. If his face isn't instantly recognizable, that's because he leads a significantly less public existence than his younger brother and sister, Jaden and Willow.
This doesn't mean he's
never dabbled in entertainment, he has. When he was just five years old, he starred in Will Smith's video, "Just The Two Of Us." Currently, he works as a DJ, who has over 600,000 Instagram followers. He also appears frequently on Will Smith's successful Youtube Channel. In addition to those things, he's also been credited in helping his brother and sister with their various musical endeavors.
He is currently worth $2 million. Not bad at all for the "unknown" Smith.
