Jack Black, Julie Bowen, Jonah Hill and Jeff Probst plan to curl up with a good book on Sunday for a good cause.

Milk and Bookies, an L.A.-based nonprofit that promotes literacy, is hosting its second annual Story Time Celebration at the Skirball Center. The event mixes celebrity readers, story-inspired arts and photo flipbooks — along with milk and cookies, of course.

Milk and Bookies hosts events around the country in which children are encouraged to purchase and inscribe books to be donated to schools and other orgs that distribute them to underprivileged kids. About 1,000 tickets have been sold to this year’s Skirball event, which will also feature Jennie Garth, Maya Rudolph and DJ Lance Rock of “Yo Gabba Gabba” fame.

Meredith Alexander, a Los Angeles mother of two, started Milk and Bookies in 2004. In 2009, the org’s scope expanded with the help of board members Heidi Fugeman Lindelof and Laura Zimmerman.

“As I was starting my family, I really wanted to spend time doing things that were really meaningful, and I found a lack of those kinds of activities around the city,” says Alexander, who is the org’s exec director. “We hope that the Milk and Bookies experience gets (kids) switched on to how great it feels to give back.”
