EXCLUSIVE: Nothing’s official yet, but I’m expecting Cameron Diaz to have a deal shortly to star in Lionsgate’s What to Expect When You’re Expecting, the Kirk Jones-directed romantic comedy adaptation of Heidi Murkoff’s bestselling how-to manual. The pic has a script by Heather Hach and Shauna Cross. Phoenix Pictures’ Mike Medavoy, Arnie Messer and David Thwaites are producing, and Doug McKay is co-producer. Murkoff and husband Erik Murkoff are exec producers with Alan Nevins. The idea is to take a book that has sold north of 16 million copies, and turn into a pic in the vein of Love Actually, where five couples experience the surprises that happen when a stork visit is imminent.

Diaz just started production today alongside Colin Firth in Gambit, the Michael Hoffman-directed caper comedy that was scripted by Joel and Ethan Coen. Shooting on What To Expect When You’re Expecting will begin in July. Diaz is repped by CAA and Rick Yorn.
