Rodriguez, Vieth's fiance, welcomed their first child, Ava, in February, after being put on bed rest weeks prior, and sadly, her medical struggles appear far from over.

On Friday, Barney updated fans on Rodriguez's condition, revealing she had a total of five blood clots in her lungs.

"Thank you for all the prayers for @sarahrod77 And please keep them coming," she wrote. "She has 3 large blood clots in one lung and 2 in the other. She also has some swelling around her heart. I love you Sarah and im so sorry I'm not there. Get well sweetie."

Along with a photo of Ava, Barney added, "At hospital visiting mommy. Get better mommy #AvasMommy."

After Rodriguez gave birth, Barney told fans she was beginning to plan their wedding. However, at this point, no official date for the Vieth/Rodriguez affair has been released.

The Real Housewives of Orange County returns to Bravo for season 10 later this year.
