The singer jetted over to Australia this week to make a surprise late appearance on the ITV show, and yesterday he was pictured making the most of his final days of freedom.
Jake headed to Surfers Paradise for some sun and fun and a dip in the ocean on Tuesday (19 November).
Looking very Baywatch-esque there with your red trunks, Jake! David Hasselhoff would be proud!
Chatting ahead of entering the jungle, the X Factor contestant said he was more interested in having a fun experience than winning.
"Oh, I don't want to think about winning. If you do win it, it is acceptance that people like you for who you are. But I am not going in there to win. This is all about having fun."
"I am going to take this opportunity with both hands. I want to relish everything that is thrown at me. I actually haven't stopped grinning since I got offered this... And I will look forward to getting my teeth into everything - but who knows what I am getting my teeth into?!"
Eek, we dread to think!
As well as Jake entering the jungle, we'll see Edwina Currie heading in with them. Their entrances come as TOWIE star Gemma Collins quit after struggling with conditions, and Corrie's Craig Charles pulled out following the death of his brother.
