What to Expect When You're Expecting London Premiere Pictures

Cameron Diaz and several of her What to Expect When You're Expecting co-stars hit the red carpet in London today to bring the romantic comedy to England. Cameron sported a sexy, strapless Stella McCartney jumpsuit for the British unveiling of the film. She's been busy promoting the adaptation of the best-selling book in the States for several weeks already. Cameron stopped by Chelsea Lately to dish on her own feelings about family and motherhood, and also teamed up with her co-star Jennifer Lopez to pay a visit to The Ellen DeGeneres Show.

Jennifer had to skip the overseas trip this week and stay put in LA for the finale episodes of American Idol, which air tonight and tomorrow. While Jennifer missed out on today's festivities, Anna Kendrick, in Christian Dior, and Chace Crawford, who play a couple in the movie, were on hand. So were Matthew Morrison, Cameron's love interest in the movie, and Rodrigo Santoro, who plays J Lo's husband.
