Gibson Dunn & Crutcher is taking a headline role on a defamation claim involving US comedian Jerry Seinfield, reports The American Lawyer.

The case started earlier this year when Missy Chase Lapine, author of cookbook The Sneaky Chef, sued Seinfeld’s wife, Jessica Seinfeld. Lapine claimed that Seinfeld had plagiarised The Sneaky Chef when she wrote her own book, Deceptively Delicious, on how to get kids to eat their vegetables.
