The Seinfeld creator reportedly asked Gervais to guest star on the eighth season of the HBO series. The pair recently teamed up on Jerry Seinfeld's NBC pilot The Marriage Ref.
"I think Ricky Gervais is one of the funniest guys I've ever met," David told E Online.
Although David has not officially confirmed the return of Curb for another season, the actor-writer has said that he is "already working on some stuff" for the series and will "probably know something in a month or so".
Ricky Gervais has yet to confirm his involvement in the series.
