The fourth season of 90210, an American television series, premiered on Tuesday September 13, 2011.
Trevor Donovan was dropped as a regular, as a result of ongoing changes by the new showrunners. He returned as a guest star in the fall to conclude his storyline. However, in late February 2012, it was reported that Donovan would return near the end of the season.[1] The CW ordered two additional episodes for the season, which total at 24. It has also been announced that the show got a fifth and final season.[2]
Season four opened to a 0.9 rating in adults 18–49, even with last season premiere. The series returned from its mid-season break on January 17, 2012, one week later than originally announced.
