Former Real Housewives of Melbourne star Pettifleur Berenger has revealed the real reason she isn't returning to the hit Foxtel reality show.

The property developer, who became a fan-favourite when she joined in season two, told Confidential she will return to TV once she resolves a serious personal matter.

"I am humbled by the disappointment of my fans that I am not returning to RHOM this season," she said. "However I can promise them that I will be returning to TV when I have taken care of some very important issues that I can't discuss right now for legal reasons."

In 2018, Berenger, 55, was embroiled in a bitter split with her defacto partner, Frank Palazzo, who tried to evict her from his multimillion-dollar Melbourne CBD apartment.

Last week, RHOM's new cast was revealed with former TV presenter Anjali Rao joining alongside yoga instructor Cherry Dipietrantonio and businesswoman Kyla Kirkpatrick. Returning to the show are "singer/songwriter" Gamble Breaux, outspoken barrister Gina Liano, businesswoman Janet Roach and food lover Lydia Schiavello.
