Megan Fox has joined the ensemble comedy Friends with Kids. Written, produced, and directed by Jennifer Westfeldt (Kissing Jessica Stein), the film “revolves around a pair of thirtysomething best friends who observe the toll that having kids has taken on the couples they know and resolve to bypass that stress by having a child and then date other people.” Adam Scott and Westfeldt will play the lead couple, Jon Hamm (who will also produce) and Kristen Wiig will play another couple. The third couple has yet to be cast. According to THR, “Fox will play a girl who Scott begins to date.” Mike Nichols and Jake Kasdan are executive producing. The film is due out in April.
