Drew Barrymore, Reese Witherspoon and Cameron Diaz just got schooled in cooking class!

The A-listers and friends gathered a group of gals including Leslie Fremar and celebrity makeup artists Lona Vigi and Gucci Westman for a girls trip to the Cooking of Italy event at the Culinary Institute of America in California's Napa Valley on Wednesday.

Cameron, who has been busy promoting The Body Book, took to Twitter to show some yummy pics of herself and friends. Along with a pic of the gals in their aprons, the leggy blonde wrote, "What an amazingly delicious, educational, and ridiculously FUN time I had with these awesome ladies!!!"

During the class, Reese made spinach ricotta raviolis and fresh pasta, while the pregnant Drew made a tasty flatbread.

Sounds like a scrumptious Wednesday!
