"Big News! Picked up! Renewed! #KATHY back in January!" Griffin tweeted on Thursday.
Added Frances Berwick, President of Bravo Media: "Bravo's relationship with Kathy Griffin has outlasted Katie and Tom's, Ashton and Demi's, and while we won't be couch jumping, we continue to be in awe of her quick wit, rude humor and spot-on analysis of pop culture and celebrity happenings," she said in a statement.
Griffin, 51, was recently nominated for an Emmy for her standup special Tired Hooker.
