O'Donnell praises 'Little Britain USA'

Rex Features

Rosie O'Donnell has called the American version of Little Britain "the funniest show ever".

The US TV star will appear in the sketch show as a member of Marjorie Dawes's Fat Fighters club.

In a brief posting on her website, O'Donnell said: "This is the funniest show. Ever. Fair warning - a few curses. I am in the third sketch."

Former Friends star David Schwimmer is also involved in the remake, directing in-studio segments for the comedy.

Little Britain makes its Stateside bow on September 28 at 10.30pm on HBO.
