Although rapper Lil Wayne spent most of last year behind bars due to a weapons possession charge he still managed to make Forbes’ distinguished list of “Best-Paid Celebrities Under 30.”

Forbes’ list takes into account the amount of money each celebrity made between May 2010 and May 2011. The list is comprised of 20 celebrities from the worlds of music, sports, and movies.

According to Forbes, Lil Wayne was estimated to have made about $15 million in the past year.

The 28-year-old rapper was joined on the list by the likes of Katy Perry, Rihanna, Justin Bieber, LeBron James, and Beyoncé Knowles. And although Beyoncé made it on to Forbes’ list the magazine described the singer as being “unusually low” on their list due to the fact that she hasn’t toured or released an album in about a year.

Topping the list of “Best-Paid Celebrities Under 30” is of course Lady Gaga who raked in a jaw-dropping $90 million primarily due to album sales, her Monster Ball Tour, and a slew of endorsements.
