The comedy show, which originally ran on the BBC from 1989 until 1998, is set to return in the spring for a special eight-part series.
It sees Pauline, 54, and Linda, 55, reprise their roles as sisters Sharon and Tracey, who share a home in the Essex town of Chigwell after their husband are sent to prison.
Lesley, 67, has also returned as the girls' man-eater friend Dorien Green.
The originally show was axed in 1998 after more than 100 episodes. The new series has been written by the original creators Laurence Marks and Maurice Gran.
Mr Marks revealed earlier this year that they went to ITV for the new series because of the BBC's policy not to make revival series.

Of the new episodes he said, "I can't give away too many secrets, but I can say that girls have moved with the times and live very much in 2013. They use the internet and tweet.
"Thatcherism was the prevailing doctrine when the Birds were first introduced to the British public, now it is Cameronism.
"The financial crash and recession have made life hard for the likes of Tracey and Sharon. They duck and dive and try to make ends meet."
