TVLine Items: TBS Orders (Much) More Conan, New Girl Nabs Big Love Sister-Wife and More!

Showing a lot of faith in its resident ginger, TBS has extended Conan O’Brien‘s late-night hit, Conan, through April 2014.

“I am excited to continue my run with TBS because they have been fantastic partners,” O’Brien said in a statement Wednesday. “This means I’ll be taping episodes of Conan well into the Ron Paul presidency.”

Conan debuted in November 2010, nearly a year after O’Brien’s controversial ouster from NBC’s Tonight Show.
