Cameron Diaz put her arm around Gwyneth Paltrow after a dinner date at Sugarfish in Brentwood, CA, last night. Gwyneth's husband, Chris Martin, also joined them for the meal. It was the latest meetup for Cameron and Gwyneth, who got together to celebrate Gwyneth's 40th birthday in NYC earlier this month and also paired up to record a funny rap for their pal Chelsea Handler. Gwyneth, who is featured in the new trailer for Iron Man 3, was without her best girlfriend last week, though, when she attended the Golden Heart Gala in the Big Apple. Cameron, meanwhile, has been spotted shopping in her time off from filming The Counselor overseas.
