Little Britain USA, slated to premiere on American pay TV network HBO in September, introduces several new characters created by award-winning comedians David Walliams and Matt Lucas - and many of them sound just as crude as fans would expect from the blackly humorous series.

According to British paper The Daily Mail, the fresh faces include Tom and Mark, bodybuilders who frolic naked in their gym - showing off their sizeable muscles and, er, other assets - while boasting about their female conquests.

Walliams described the characters as "possibly the most outrageous we've ever done".

Walliams and Lucas will continue the Little Britain tradition of donning dresses: in one new sketch Lucas plays an unfortunate-looking little girl with aspirations of winning beauty pagents, while Walliams plays her bossy mother.

Another new character is Bing Gordyn, "the eighth man on the moon", who's bitter about the lack of recognition he has received for his achievement.

Little Britain favourites such as foul-mouthed schoolgirl Vicki Pollard, political aide Sebastian Love and Harvey - a British aristocrat whose parents still breastfeed him and wipe his bottom - will also make a return.
