''Curb Your Enthusiasm" may be nearing an end. Two producers of the popular Larry David HBO comedy hinted on social media that production had wrapped on the series for good after 12 seasons. One of the producers, Jon Hayman, has since deleted his Tweet. “Variety” reports that David's contract with HBO is ending this year. The show has been known to take long breaks in the past, once going on hiatus for six years before 2018's Season Nine.
