Cameron Diaz  joined up with her A-list friends to attend Baby Buggy's Summer Dinner in the Hamptons on Saturday. The bash, which was hosted by Jessica and Jerry Seinfeld , counted Kelly Ripa , Mark Consuelos, Alec Baldwin , and Naomi Watts  among the guests. Naomi, Cameron, and Jessica all wore Rag & Bone , which also served as a sponsor for the dinner. All the partying was for a good cause, as Baby Buggy helps raise money for families in need with young children.
This isn't Cameron's first trip to the Hamptons this year as she also visited the tony Summer spot to film scenes for her latest project, The Other Woman, with Kate Upton and Leslie Mann. The trio has been shooting scenes all over NYC over the past few months, but they did get to escape to the Bahamas last week to film bikini scenes  for the new flick.
