Comedienne Kathy Griffin's Tv talk show has been axed.

The Emmy Award winner's weekly series Kathy, which premiered last spring (12), has been shelved after just 24 episodes aired on U.S. network Bravo.

The final episode was broadcast on 28 March (13), with an average of 500,000 viewers.

Griffin took to her Twitter.com page to confirm the news, telling followers, "Sad but tru (sic)."

The outspoken funnywoman has previously enjoyed success on Bravo - her reality show, Kathy Griffin: My Life on the D-List, aired for six seasons before wrapping in 2010.
