Joanna Krupa has had it with Brandi Glanville.

On Thursday TMZ reported the Real Housewives Of Miami star filed a defamation suit against the Real Housewives Of Beverly Hills standout.

The Polish siren is reportedly upset that Glanville said her private parts smelled when she was appearing on Andy Cohen's Watch What Happens Live in December.

On Monday Life&Style reported that Krupa was ramping up to sue the acid tongued diva. Joanna fired off a legal letter informing her Beverly Hills counterpart that she intends to sue.

In documents obtained by the magazine, the 35-year-old model's lawyer informs Brandi that his client plans to launch a civil suit in Florida against the reality star for 'slander, libel, defamation and/or intentional inflection of emotional distress'.

While the pair has long traded barbs on social media, things turned really sour in November 2013 when Brandi accused Joanna of having an affair with her co-star Yolanda Foster's then-husband Mohamed Hadid.

Brandi made the accusation on Andy Cohen's Watch What Happens Live after hearing what Joanna had said about her on Twitter - but she was not done there.

Below-the-belt remarks: The 42-year-old rather crassly said her reality star rival's private parts smelt

In addition to saying the model had slept with the property tycoon while he was still married, Brandi rather crassly said her reality star rival's private parts smelt.

The 42-year-old said: 'Well Mohamed did tell me that her p***y smelt.'

'It's true I'm not lying and Lisa Vanderpump was there when he said it, sorry b**h.'

Last month, the letter says, Brandi made reference to Joanna again saying 'you can't help odour situations'.

Joanna's lawyer Raymond J. Rafool said there is no way Brandi could not have expected these comments to be hurtful.

He wrote: 'You knew your statements were false and that such were damaging and humiliating to Mrs. Krupa and/or her husband and subjected Mrs. Krupa... to hatred, ridicule, contempt and/or injury...'

The lawyer accuses the reality star of making the 'malicious and false statements' to make herself a bigger star.

No filter: Brandi made the accusation on Andy Cohen's Watch What Happens Live after hearing what Joanna had said about her on Twitter

'It appears you make false statements about Mrs. Krupa to make yourself marketable and to associate your name with a celebrity in an attempt to ''tag'' yourself with her for media and personal searches and to create a brand for yourself for monetary and attempted celebrity status.'

Speaking of the below-the-belt comments, Joanna told the magazine: 'She doesn't even know me.'

An insider added that the reality star was at her wit's end after the comments came up again.

The source said: 'Joanna hired a heavyweight lawyer Ray Rafool to sue as enough is enough.'
