Gyllenspoon Double Dates with Cam and Gerard

If you hit up L.A.'s Chateau Marmont, you're bound to catch a celeb sighting, but four in one night is really a surprising treat! Actresses Reese Witherspoon, 32, and Cameron Diaz, 35, popped into the hotspot together with their current man candy -- Jake Gyllenhaal, 27, and Diaz's new flame, Gerard Butler, 38! The A-list foursome arrived at 12:30 AM, and noshed on red wine and appetizers on the patio. A source tells Life & Style, "Cam snuggled up to Gerard and rested her head on his shoulder. Jake and Reese were... joking a lot and just very comfortable with each other." Click on an image to view the CAMERON DIAZ photo gallery! (link)
