BIRDS Of A Feather favourites Linda Robson and Pauline Quirke have fallen out after 50 years, a source has claimed.
An insider says "real and tense issues" resulted in Pauline refusing to take part in the classic sitcom's 30th anniversary show in 2019.
Loose Women favourite Linda, 62, and Pauline, 61, shot to fame on Birds Of A Feather as Essex girls Tracey and Sharon, whose husbands were both jailed for robbery.
Alongside Lesley Joseph, who played their snooty neighbour Dorien, the trio became huge sitcom stars in the 80s and 90s.
The show recently returned for a Christmas comeback but without Pauline, whose character was written out as "stuck on a COVID cruise".
Now a source has told the : "Both Linda and Lesley were saddened that Pauline didn't want to return to make a 30th anniversary episode.
"Linda and Pauline used to be very close, less so Pauline and Lesley.
"I think Pauline resented the attention that Lesley got and it was very tense and difficult to navigate at times.
"Pauline wasn't approached about the Christmas special. The atmosphere on the set had previously become difficult, there were real and tense issues."
Last year, Linda spoke about her long friendship with Pauline, saying: 'We were friends from ten years of age.

'We went to the same primary school and we started taking acting classes together.
"We were known as the real kids, or the cockney kids off the street. We've both been really good friends, and we're still working 52 years later."
Linda joined the line-up of Loose Women and quickly became a hit with fans of the show, where she is nicknamed 'Nanny'.
Pauline meanwhile went into more serious acting and won huge acclaim for her gritty role in hit drama Broadchurch.
The Sun has contacted a rep for Pauline.
