The 42-year-old was performing at 'a sold out crowd at Madison square garden' the night before he was taken to hospital.
Pictured in a hospital bed, with a mask on, Cannon told his followers: "Okay, so I guess I’m not Superman…
"I promised myself I would never be back at this place again…
"But this is a great lesson to take care of YOU or YOU won’t be able to take care of everyone else.
"Don’t trip though, I don’t need any well wishes or prayers, just some solid rest and I will be back on the journey to becoming stronger than ever… it’s just pneumonia, nothing I can’t handle.
"Crazy thing is, last night we was just rocking a sold out crowd at Madison square garden in front of thousands of fans, now I’m all alone in a tiny hospital room.
"Life is definitely a rollercoaster! #LupusWarrior."
Cannon was diagnosed with lupus back in 2012. There is currently no cure for the auto-immune condition, with symptoms often appearing in cycles of relapses and remission.
The TV personality recently announced that he is expecting a 12th child, as reported by Entertainment Weekly.
In a post showing off her bump, partner Alyssa Scott wrote: "With you by my side."
One user said: "Omg, congratulations, love and blessings to you!"
Another wrote: "I knew it! So happy for you! This is such blessings!"
The couple's son Zen was diagnosed with brain cancer and tragically died at just five months old back in December 2021.
The news came just a few weeks after Cannon welcomed his 10th child.
He and Brittany Bell, who already shared two children together, Golden Sagon and Powerful Queen, announced that they had had a third, named Rise Messiah.
Cannon wrote: "Another Blessing!!! As my journey on this planet becomes more and more remarkable and unfathomable, all I can do is thank God and continue to ask the Most High to order my steps.
"He has given me stewardship and dominion over a family dynamic that to some is unimaginable.
"But more importantly he has blessed me with loving individuals to guide me with care through this purposeful life.
"I am so indebted and grateful for the matriarch energy in my time of need."
He concluded: "Probably the most difficult labor and delivery I have ever witnessed!.
"48 hours of excruciating pain and life risking danger to welcome 10 pounds of Love and joy named RISE MESSIAH CANNON."
