At their height, the Stock Aitken Waterman trio helped propel the likes of Kylie Minogue to global stardom.
But as the Daily Mail reports, a Bananarama singer has accused the legendary producers of sexism.
Siobhan Fahey says the treatment she experienced at their hands was partly behind her decision to quit the chart- topping girl group in 1988.
The 59-year-old, who co-founded Bananarama with friends Sara Dallin and Keren Woodward in 1981, revealed the tension between her and Pete Waterman became so great that she could not bear to be in the same room as him.
The songwriting partnership of Mike Stock, Matt Aitken and Waterman were nicknamed the Hit Factory, selling 40million records, and in 1986, Bananarama made them their main producers after working on the smash hit Venus together.
