Jake told fans he had managed to "pull a smile" in return for all of the well-wishes he has received since his emergency admission in Marbella, Spain, yesterday (31 May).
However, while on the mend, he has also let on to the seriousness of his condition.
In a close-up shot, posted to Instagram, Jake said: "Managed to pull a smile for all the amazing people who sent nothing but love and wishing me better.
"Your support has got me through this worrying time but, as I said, you can't get rid me that easy!
"I'm slowly getting better, my family @chloelewis91 and close friends have been here for me and love them very much."
Jake finished his message with: "Gonna get a bit more rest now."
News of Jake's hospital admission broke yesterday and it was accompanied by reports that he had allegedly been 'stabbed in a nightclub'.
Earlier on today, Jake broke his silence by sharing another picture of himself, this time pulling a thumbs up in hospital.
Since then, his ex-girlfriend Chloe Lewis has spoken out and revealed she has been at Jake's bedside since he was admitted to hospital. Although Chloe confirmed they are not back together, she told her Instagram followers that she "still cares" for Jake.
Jake's rep has confirmed his hospital admission, however he declined to comment on the reason behind it.
