Larry and Laurie David Curb Their Marriage

Crankypants "Seinfeld" co-creator Larry David and tree-hugging activist wife Laurie David are calling it quits on their marriage.

Larry and Laurie have separated after 14 years -- and two children -- according to Page Six. Though the Post's report says that the official word is "very amicable, and no other parties are involved," the announcement follows closely upon "An Inconvenient Truth" co-producer Laurie's well-publicized tour of the US with rocker Sheryl Crow, who just adopted a child.

David made an estimated $200 million on "Seinfeld." Laurie's "An Inconvenient Truth," the enviro-crusading documentary, has made an estimated $24 million since its release a year ago.
