Fabulous causes deserve equally fabulous events, and Oceana’s Endless Summer Party is shaping up to be just that.

Oceana, the largest international organization focused solely on ocean conservation, promises loads of celebrity guests, performers, and a stunning location. The party, set for Saturday, November 13, will take place at the Esquire House in Los Angeles; an $18.9 million, 9,000-square-foot estate in the Hollywood Hills— yowza!

Official Oceana Ambassador Adrian Grenier is set to perform with his band, The Honey Brothers. And intimate performances by Jeff Goldblum & The Mildred Snitzer Orchestra are slated as well. In addition, familiar faces like Anthony LaPaglia, Christine Woods, Daphne Zuniga, Jenna Ushkowitz, Lake Bell, Leonor Varela, Liam Hemsworth, Max Burkholder, Sally Pressman, and Simon Helberg will be in attendance, which means a whole lot of stars helping to raise some serious cash.

Tickets are still available, and all proceeds go toward Oceana’s work to protect the world’s oceans. A pretty deserving cause considering that oceans make up roughly 70 percent of our planet, and if we want to keep our 30 percent in top shape, we better take care of the water surrounding us.
