Jamie Foxx’s mystery hospitalisation was due to the actor being stricken with a “bad headache” that left him “gone” for nearly three weeks.

The ‘Ray’ Oscar-winner, 56, has kept the reason for his mystery hospitalisation under wraps until now, after his daughter Corinne Foxx, 30, revealed on April 12 last year he had “experienced a medical complication” but that “due to quick action and great care,” he was “already on his way to recovery”.

Jamie has now been recorded by fans in Phoenix saying that a day before his girl’s announcement he suffered an excruciating headache and asked his “boy for Advil”.

He is then seen on the footage snapping his fingers as he said: “I was gone for 20 days.”

Jamie added he does not “remember anything” about his illness.

He also said he was in Atlanta when he was hospitalised, adding his sister and daughter took him to “the first doctor” they could find.

Jamie went on: “Next doctor said, ‘There’s something going on up there.”

But he said about his head condition: “I won’t say it on camera.”

Three weeks after his daughter’s initial announcement about his medical emergency, Jamie posted a message on his Instagram Story that said: “Appreciate all the love!!! Feeling blessed (praying hands, red heart and fox emojis.)”

When rumours of what may have happened to him began circulating online, Corinne updated fans to say her father had been “out of the hospital for weeks, recuperating.”

She added: “In fact, he was playing pickleball yesterday!”

It wasn’t until last July Jamie gave more details about his condition, saying it was a “hellish” experience.

But he did not reveal any diagnosis.

He added: “I went through something I thought I would never, ever go through.”

But he stressed he was never left “blind” or “paralysed”.

Jamie added with tears in his eyes in his selfie-style video update: “I know a lot of people were waiting or wanting to hear an update, but to be honest with you, I didn’t want you to see me like that, man.

“I didn’t want you to see me with tubes running out of me and trying to figure out if I was going to make it through.”

Jamie was seen returning to shooting the ‘Back in Action’ film with co-star Cameron Diaz, 51, in Atlanta in January – the movie he had been shooting when he fell ill.
