Drew Barrymore and gal-pals Cameron Diaz and Reese Withersoon are spending their girls' trip learning some tips and tricks in the kitchen.

E! News has learned that the trio of A-listers jetted off to Napa Valley in Northern California to experience the "Cooking of Italy" at the Culinary Institute of America with Hollywood stylist Leslie Fremar and celebrity makeup artists Lona Vigi and Gucci Westman for two days.

"What an amazingly delicious, educational, and ridiculously FUN time I had with these awesome ladies!!! @gucciwestman @reesewitherspoon @drewbarrymore @lesliefremar @lonavigi @oilandsalt @jal14 @ladyfredriksz #CIA #napavalley #culinarylove #goodfoodgoodfriends#GT14," Diaz wrote on Instagram with a snapshot of the group.

Meanwhile, Witherspoon shared a photo of herself, decked out in her chef gear, while making "spinach ricotta raviolis and fresh pasta!! #CIA#GT2014."

Barrymore also shared an Instagram photo of different culinary dishes ranging from salmon to oranges and pasta dinners.

"Going to culinary school in napa ! #freshpasta #learning #eating," she captioned the kitchen shot. In the photo collage, Barrymore posed with the pasta dough before it's made into shapes. Another image shows the dough laid out and cut into strips on a stone counter top before getting presented all ready to eat in a bowl.

So when are we invited for dinner, ladies?!
