Ananova:

Channel 4 producers are looking for "unusual" families to take part in the next series of Wife Swap.

An insider told The Sun they're considering recruiting naturists and lesbian and gay couples.

The radical move follows the phenomenal success of the reality show.

Five million viewers tuned in last Wednesday to see housewife Tracy swap her mansion for single mum Shaz's East London council flat.

An insider on the show said: "We are already working on the next series and have been looking at more unusual families, including naturists and gay couples."
