I feel very fortunate to have good friends: Cameron Diaz

Los Angeles: Actress Cameron Diaz says she feels very fortunate to have the support and company of her reliable friends.

The 41-year-old actress recently enjoyed a "girls trip" to Napa Valley in California with Drew Barrymore and Reese Witherspoon. They took a cooking class together at the Culinary Institute of America in St Helena, reportedly.

"I exist for all my girlfriends. I am very, very, very fortunate, my friends are incredible and I am very lucky to have a lot of really solid, good friends," Diaz said.

The `Bad Teacher` star, who is very health conscious, released her first publication, `The Body Book` in December last year.

The actress had previously said that she was inspired by Gwyneth Paltrow and Drew, who too had penned some books in the past.
