If you want to check out some celebrities catching some waves for a cause, head down to Malibu on Sept. 12 for the Surfrider Foundation’s 4th annual Celebrity Expression Session.

The event will be held at First Point, Surfrider Beach in Malibu as part of the Malibu Surfing Association’s MSA Classic invitational contest.

The Celebrity Expression Session allows celebrities to show off their surfing skills and moves in a free surf format, while raising funds and awareness for the Surfrider Foundation.  Past participants including Jason Mraz, Sal Masekela, David Chokachi, Minnie Driver, Flea and Brandon Boyd have raised more than $5,000 for the foundation and its continued efforts to protect our coastlines.

Here’s more from the press release:

“This isn’t some wingy ‘push the celebrity into a wave’ type of event,” says Matt McClain, Surfrider Foundation’s Director of Marketing and Communications.  “These guys are going to be out there working First Point to raise money to help keep our oceans, waves and beaches clean.”

The MSA Classic – the premier contest in the Coalition of Surfing Clubs annual series – will host the Surfrider Foundation’s Celebrity Expression Session for the second year in a row.  The MSA Classic, first held in 1962, now has over 275 athletes representing elite surfing clubs from around the world.

Admission to the Surfrider Foundation Celebrity Expression Session and MSA Classic are free.
