The former Made In Chelsea star appeared on last year's series, but left the jungle after just three days when it was discovered he'd been taking steroid pills.
He apologised at the time for his "serious error in judgment" and said he'd been taking the pills ahead of a charity boxing match that never actually happened. Show bosses withdrew him from the show as it would be "unsafe" for him to stay.
But could he get a second chance?
When asked, Spencer told The Sun on Sunday: "It's been discussed. I'd like to do it. I made a terrible mistake and I apologised. I'm in a good place now."
His statement after leaving the show had read: "I screwed up, and have some explaining to do. Shortly after I arrived in Australia I told the production team that I was taking a steroid-based medication that had begun some weeks ago.
"When I started taking this programme of pills it was in preparation for a charity boxing match which, ironically, never took place. Vanity, I suppose, had been the reason for wanting to bulk up a bit for the fight. I had intended to come off the pills gradually, but there was no time to do this before I reached the jungle.
"My admission to the production team that I was still taking these pills led to the conclusion that it would be unsafe for me to stay in the jungle - a decision which I found extremely hard to stomach. I pushed back but ultimately the show's duty of care prevailed and bags had to be packed."
Since being forced off I'm A Celebrity, the reality star has been working hard to regain his health. When he disappeared from the limelight, there were rumours he'd checked into a rehab facility, but he later told BBC News he'd actually been in Africa, helping build schools in Tanzania.
"I wanted to selflessly do something and give back," he explained. "I was in a muddled place. I found a building project in Tanzania to build a school for Masai children so more local kids could go to school in that area."
He added to Loose Women recently: "Ultimately I made a very stupid mistake, and it's my own fault and ITV did what they had to do and unfortunately I found myself of the plane home. I really hope one day to get another shot at it."
