A source told Access on Thursday that the reality couple, who left the show in a whirlwind of events that included the pair quitting three times, trying to return to the competition, spending a night in the show's Lost Chamber and finally heading back to LA after Heidi landed in the hospital – will head back to Costa Rica on Sunday or Monday.
The finale will air on Wednesday, June 24.
On Monday, Spencer and Heidi told Access that they were under doctor's orders not to bring Heidi back to the jungle.
"We tried to go back," Heidi said. "I was really sick, and we wanted to try to go back for the charity and finish it, but my doctor said I couldn't and the show didn't want to have us back for my health risk."
And she added that her illness was definitely not fake.
"It was one of the worst experiences of my life," she said. "The doctor was telling me it was an emergency, that it was a life-threatening health risk. I was throwing up 10 to 20 times the first night and the second day. Honestly, at one point I was like, maybe this is it."
Still, she said, the couple's brief time on the show was worthwhile.
"It was a great life experience," Heidi said. "I would rate it, you know, a 10. Would I do it again? Probably."
