The third season of The New Adventures of Old Christine premiered on February 4, 2008 and concluded on March 31, 2008. It was originally intended to have 13 episodes, since CBS scheduled the series as a midseason replacement, but due to the Writer's Strike, it was shortened to 10 episodes.
This season marks the reunion between Julia Louis-Dreyfus and Jason Alexander, who previously worked together in Seinfeld.
In this season, Christine and Mr. Harris have a smooth going relationship, until Christine's schedule becomes too hectic midway through the season causing Mr. Harris to leave her. Meanwhile, Richard and New Christine take their relationship up a notch and buy a house together, which coincidentally is Christine's dream house leaving her feeling jealous and confused. Barb leaves her husband and she has a short-lived fling with Matthew much to Christine's horror.
