Riposte: Foster slammed Lisa Rinna in blog post on Tuesday night after she suggested she was faking her Lyme disease on RHOBH

This comes after Foster talked about Lisa Rinna on her blog following Tuesday night's Real Housewives of Beverly Hills. 

In her post, the ex-model calmly declared she didn't blame the former Melrose Place star for brushing off her Lyme disease.

But readers didn't have to look too closely between the lines to decipher Yolanda's summation of Rinna to be an ignorant, wine-swilling, uneducated. 

It was never a secret not all of the 51-year-old's cast-mates bought into her diagnosis with the mysterious debilitating illness.

But on Tuesday night's episode of RHOBH, Rinna made very clear her opinion on Yolanda's condition

‘I feel that Yolanda’s posts on Instagram can be confusing, because one minute she’s in a hospital bed with needles in her arm and the next she’s on a yacht looking like she’s having a great time,’ said Lisa.

Fictitious disorder: Lisa read a description of Munchausen syndrome while spending time with Lisa Vanderpump and Kyle Richards

The actress then read a description of Munchausen syndrome or ‘factitious disorder’ – where people feign illness to gain attention or sympathy.

In her blog post after the show, Yolanda said several friends had reacted angrily, but she rose above it, claiming 'I am not enraged or affected anymore by what I have learned to see as human nature and the weak side of it'.

'I do wonder though why these adult women sit around drinking wine in the afternoon debating another person’s health issues?' she asked. 'As much as I wished they cared enough to learn and ask questions, I must blame it on and assume it's "ignorance".'

Feign disease: The former soap opera star suggested Yolanda was faking Lyme disease for sympathy

She even concurred with he co-star's self appraisal that she was 'only human'

'It takes a compassionate and confident woman to hold ground under social pressure - it's so much easier to take the common road and get on board the train of the misinformed and the doubtful. The negative,' she said.

'Few people have the ability to stay firm when they're not educated or spiritually centered and not feed into the negativity otherwise known as gossip. 

She added that she didn't blame Lisas Rinna and Van Der Pump or Kyle - in fact she pitied them that 'her battle was such a point of weakness for them'. 

'I'm probably the only Housewife in the entire franchise that uses this platform to bring awareness in the world rather than just money in my pocket,' she concluded. 

Ouch: Readers didn't have to look too closely between the lines to decipher Yolanda's summation of Rinna to be an ignorant, wine-swilling, uneducated, weak-willed, unbalanced, greedy gossip
