"Real Housewives of Atlanta" star Porsha Williams' cousin and "Porsha's Family Matters" co-star Yolanda Favors has died at 34.

Williams announced Favors' death in an Instagram tribute posted Sunday, opening with an E.A. Bucchianeri quote: "So it’s true, when all is said and done, grief is the price we pay for love."

Favors died Aug. 7, weeks before her 35th birthday.

Her caption of a photo tribute to Favors continued: "Londie - you were our best friend, our sister, our aunt, our cousin, and so much more. Your life was a blessing, your memory a treasure, and you are loved beyond words and will be missed beyond measure."

A cause of death has not been announced. USA TODAY has reached out to Williams' reps for comment.

"Porsha's Family Matters" followed the "The Real Housewives of Atlanta" star amid her sudden engagement to Simon Guobadia and featured her extended family as vocal participants in her personal drama.

The "Housewives" spinoff lasted one season, from late 2021 to early 2022.

"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. For that, we’re eternally grateful," Williams said. "Love you always Dear Baby Cousin."

Williams filed to divorce Guobadia earlier this year after 15 months of marriage. The reality star is set to return to "RHOA" and is currently filming Season 16, along with Phaedra Parks, Shamea Morton Mwangi and Drew Sidora with newbies Brittany Eady, Angela Oakley and Kelli Ferrell.

In her February filing, Williams states that she and Guobadia "are currently living in a bona fide state of separation" and also requests that the court enforce the prenuptial agreement the couple entered into on Nov. 17, 2022, a few days before they were married on Nov. 22, 2022.

In May 2021, the couple went public, with Williams confirming her "beautiful" new relationship with Guobadia, who is the ex-husband of her "Real Housewives of Atlanta" co-star Falynn Pina, in an Instagram post.

Williams said she understood the "optics" but wrote that Simon Guobadia's divorce from Falynn Pina was finalized and she had nothing to do with the split.

"Our relationship began a month ago — yes we are crazy in love. I know it’s fast but we are living life each day to its fullest," Williams captioned the photo of her and Guobadia. "I choose happiness every morning and every night. Tuning out all negative energy and only focused on positive wishes."
