Meanwhile, Gosselin is also having to defend herself these days as she's slamming rumors that she "bullies" her family. She recently went on a Twitter rampage, retweeting messages of support from her fans.

The celebrity mother is retaliating against a new tell-all book by author Robert Hoffman that suggests Gosselin is a "bully" that physically reprimands her children and was so cruel to her family animals, that she left them in cages for hours without food.

Still, Gosselin doesn't seem to be fazed as she has been looking to her family and friends along with her fans for support.

"Who needs a rag tag pap inspired "tell all?" U have "told us all" we need 2know by sharing the beauty of ur well adjusted kids!" one Twitter user wrote.

Another one added, "Kate, it shows that you can be amused by the insane things that tabloids think up, your feet have never been so grounded."

Gosselin separated from her ex-husband Jon Gosselin in 2009 before officially divorcing him in 2010.
