Net worth: $4 million

Ever heard of the show “Wizards of Waverly Place”? It’s apparently the second most popular Disney program of all time (after “Hannah Montana,” of course). For Selena Gomez, this means a hefty $30,000 per episode. And after successfully recording the theme song for “Wizards,” she formed a teen band called Selena Gomez & The Scene. The band has sold almost 2 million copies of their three albums so far.
