Cameron Diaz at a Gas Station | Pictures

Cameron Diaz stopped to fuel up at a gas station in Seal Beach, CA, yesterday. She's back on the West Coast after popping up in NYC on Saturday night for a fundraiser. Cameron posed with pal Leonardo DiCaprio at a special Tag Heuer event that benefited the UN Women and New York Cares Sandy relief effort. The duo continued the fun later that night and celebrated Leo's 38th birthday at The Darby.

Last week Cameron was in London, where she attended the opening party for Bodo's Schloss restaurant with Gwyneth Paltrow and Elle Macpherson and premiered Gambit with Colin Firth. Cameron's been on the go all month, traveling between the UK and the States, though she's staying put on the cover of Elle UK's December issue, which she posed for as part of press for Gambit.
