With the 20th anniversary of Titanic happening this year, the 1997 James Cameron-helmed movie is having a moment, again. Celiné Dion performed “My Heart Will Go On” at the Billboard Music Awards in May, Cameron is planning a National Geographic special for December, and we’re thinking about dusting off our old DVDs for a repeat viewing ASAP. Earlier this week, there was another Titanic-related event when the Leonardo DiCaprio Foundation hosted its annual gala in St. Tropez, France, and DiCaprio’s Titanic costars came out to show their support.

Sharing a snap on his Instagram, Billy Zane (who played Rose’s fiancé Cal) wrote, “Gangs back together. Now we’re saving icebergs. Go figure. @katewinsletofficial @leonardodicaprio @leonardodicapriofdn.”

Leonardo DiCaprio, Kate Winslet, and Billy Zane had a Titanic reunion

This year’s event was a fundraiser and auction that included a chance to bid on a dinner in NYC with DiCaprio and Winslet later this year. The winning bidder for the dinner date with Jack and Rose will also be supporting a GoFundMe campaign that Winslet set up to help a UK mother with her cancer treatment.

Besides the Titanic reunion, the gala featured performances by Lenny Kravitz and Madonna, who performed her 1980s hit “La Isla Bonita.” Since 2010, DiCaprio’s foundation has raised over $80 million for various environmental initiatives. The 2016 gala raised an incredible $45 million for environmental causes.
