"The program will continue to capture the incredible lives of the eight Gosselin children and their family, but will now include a deeper focus on Kate's role in the family and her journey as a single mother building the next chapter in her life," the network said in a release. "TLC will continue its exclusive relationship with Jon Gosselin and he will continue to appear on the show, but on a less regular basis."
"Given the recent changes in the family dynamics, it only makes sense for us to refresh and recalibrate the program to keep pace with the family. The family has evolved and we are attempting to evolve with it; we feel that Kate's journey really resonates with our viewers. Additionally the network is in development on a Kate project for 2010," Eileen O'Neill, TLC's president and general manager, said in a statement.
Kate Gosselin said on her Facebook page Monday that "Jon & Kate Plus 8" may not be renewed for a sixth season because of plunging ratings.
Gosselin and her husband Jon became media sensations as the stars of their own show about raising twins and sextuplets.
However, the spotlight reportedly put a strain on the couple's marriage and they recently announced plans to divorce. Jon's subsequent dates and trips to nightclubs have been well-documented by the media.
"With ratings falling, this might be the last season of 'Jon & Kate Plus 8.' I'm not sure yet," the New York Post said Gosselin wrote in a Facebook message.
The Post also noted Gosselin recently taped a pilot for a talk show with Food Network star Paula Deen, so she may continue her television career even if "Jon & Kate" isn't renewed.
