Yolanda 'Londie' Favors died at the age of 34 on Wednesday, August 7.
On Sunday, Porsha Williams announced the devastating news that her younger cousin had passed away and shared a tribute in her memory.
A cause of death for reality star, who appeared on Porsha's spinoff series Porsha's Family Matters, was not announced.
Favors would have celebrated her 35th birthday on August 21.
In memory of her younger cousin, the Real Housewives of Atlanta star shared the last photo Favors posted on her Instagram as well as a quote from author E.A. Bucchianeri.
The photo she posted of her cousin, which was a selfie Favors had posted on Instagram in 2022, was inscribed with a quote from author Renee Wood, which read: 'Your life was a blessing, your memory a treasure, and you are loved beyond words and will be missed beyond measure.'
Porsha included the same quote in her caption.
'So it's true, when all is said and done, grief is the price we pay for love,' Porsha quoted Bucchianeri as she began in a lengthy caption dedicated to Favors, who she affectionately referred to as her 'dear baby cousin.'
'Londie, you were our best friend, our sister, our aunt, our cousin, and so much more,' she wrote.
'Your life was a blessing, your memory a treasure, and you are loved beyond words and will be missed beyond measure.'
'The impact and value you provided all of us during your time here was tremendous, but we know that your spirit will always be with us every day guiding us through this difficult time and what's still to come,' she continued. 'For that, we're eternally grateful.'
She concluded her heartfelt note and wrote: 'Love you always Dear Baby Cousin. RIP.'
