Warning: spoilers ahead for Monday’s episode of Dancing with the Stars.
Zolciak-Biermann was unable to compete in Monday’s episode and will have to withdraw from competition.
“It’s the scariest thing I’ve ever been through in my whole life,” she said in a prerecorded segment.
“I’m extremely worried,” Dovolani added in the segment. “I don’t want to risk her life over a dance.”
Dovolani performed their planned I Dream of Jeanie dance with Jenna Johnson, and then Zolciak-Biermann appeared via Skype.
“I’m really sad,” Zolciak-Biermann of not being able to be there. She was well enough to dance, and she rehearsed on Saturday, but her doctors were worried about her flying. She said if she lived close enough to drive, she would have.
Tom Bergeron was the bearer of the bad news that she would not be able to continue in the competition, because the rules state that in the instance of a health issue or illness preventing a contestant from competing, the contestant must withdraw.
“Honestly, I didn’t know I was getting excused from the competition until Tom hugged me,” Dovolani told PEOPLE backstage. “But the truth is, I’m just proud of her for listening to the doctors, putting her health first, putting her family and kids first and making that the most important thing.”
On Twitter, both campaigned for fans to continue to vote for them in hopes they could continue performing.
“How disgusting for you to insinuate I ‘faked’ my mini stroke on your show this morning!!” she wrote on Instagram Monday.
After returning home Friday, she released a statement saying she was resting with her family and that he hoped she would be returning to DWTS.
“I can’t express enough how much I love dancing and this whole experience, and I hope this will not be the end of dancing,” Zolciak-Biermann said.
She struggled to impress the judges during week 1, but earned more encouragement from the judges in week 2.
