Queen Latifah -- CANCELLED

"The Queen Latifah Show" just got the ax.

The show is in its 2nd season and we're told production will be coming to a halt. Our sources say the staff was brought into an office Friday AM and given the news. The honchos weren't specific but it's all about ratings and cost.

Queen Latifah just posted a note on her Facebook page, saying to her staff, "Your dedication and sacrifice was crucial to the entire team, and in the face of intense challenges, you displayed 'True Grit.!'"

She ends by saying, "The most important thing in life is that you wake up every single day and take chances. No matter what the outcome ... believe in yourself and continue to fly."
