"Please send prayers and positive vibes to Ashley. [Her] battle with lupus has put her into kidney failure. She is in the ICU and is finally responsive," an Instagram Stories posting on Ashley's Instagram account announced on Sunday afternoon.

"Prayers for her children as well. Thank you!" continued the posting, which appears to have been written by someone else on Ashley's behalf given the third-person references.

The posting did not reveal any additional details.

However, prior to the hospitalization announcement Ashley's most recent Instagram activity appears to have been an Instagram Stories posting promoting her personalized Cameo video recordings late Saturday night, suggesting the 90 Day Fiance star's hospitalization occurred overnight.

Ashley was previously hospitalized due to lupus, a chronic autoimmune disorder, twice in December.

In early December, Ashley had revealed she had recently been hospitalized but was now home and doing better.

"Thank you so much for all your prayers and support. Your kind words are what is helping me get through this trying time. Truly appreciate each of you!" she wrote in an Instagram Story.

"I'm finally home and on the mend! Thanks again for everyone's support."

Ashley didn't dive into the details of her illness or condition, although she had previously shared she suffered from lupus.

But Jay Smith, Ashley's 90 Day Fiance co-star and husband, had confirmed her hospitalization was due to her ongoing battle with lupus when he posted two photos showing Ashley sleeping in a hospital bed.

"I promise I will always be there for you through all the ups and downs, no matter what happens. Love you babe girl get well soon #lupus #getwellsoon #staystrong," he captioned the images.

However after Christmas, Ashley had posted several more Instagram Stories in which she revealed she had been re-hospitalized due to lupus and spent the holiday in the hospital.

"If I could ask Santa for one gift it would be Good Health. Being admitted on Christmas Eve and missing Christmas morning with my children is the worst," she wrote in an Instagram Story posting.

"My strength is beginning to run out but God's strength will pull me through."

On December 22, Ashley also sparked speculation she and Jay have split when she suddenly posted a cryptic Instagram Stories photo about not being able to "fake" things anymore and 90 Day Fiance fans noticed she had also deleted all of her photos of Jay from her Instagram account.

"You can only fake that things everything is ok for so long. Then you just hit that point... - ME!!!!!" the Instagram Stories posting stated.

In addition, fans also noticed Ashley and Jay were no longer following each other on Instagram. Jay also subsequently scrubbed his Instagram account of any photos of Ashley.

Prior to Ashley's December 22 posting, Ashley and Jay's social media postings had regularly featured each other and made it clear that they were still together and living in Ashley's home in Mechanicsburg, PA.

However, Jay had urged viewers to stop speculating about his life in an Instagram Stories posting on December 29.

"Stop act like y'all know my life," he wrote.

On December 30, Jay shared a link to a newly-created GoFundMe account that was looking to raise $5,000 to "help me get and my feet an a place to stay."

The GoFundMe account had only raised $5 from a single contributor several hours after it was created, and was later removed.

According to 90 Day Fiance blogger John Yates, Jay also briefly posted an Instagram photo showing Ashley talking with a police officer outside what appeared to be her home.

"Okay Ashley call the cops... guess it's time to leave now," the 90 Day Fiance star captioned the photo, which he subsequently deleted.

Ashley later posted an Instagram Story claiming the GoFundMe was a scam and Jay had only shared the link to it "to be a smartass."

"I Spoke with Jay and neither one of us has a go fund me... he just reposted it to be a smartass! I can't watch people send money to someone scamming them," Ashley wrote.

Earlier this week, Ashley also posted another vague Instagram Stories posting that alluded to the notion she may feel like she's better off without Jay in her life.

"Everything changed the day she learned that she was just as valuable as everyone else," she wrote in the January 10 posting.
