Some viewers felt Jimmy crossed the line when he told Jake: "The more I'm getting to know you, the more I'm thinking, 'What the f*** is this p*** doing in here?'"
When former footballer Jimmy was eliminated from the jungle first, he defended himself, insisting it was just banter and that he and Jake were good friends.
And on last night's Coming Out show, we heard Jake's side of the story.
"I've made amazing mates with Foggy and Jimmy. We were the three musketeers in there. With Jimmy, it came out he was bullying. What a lie that is! We had banter and that's it!"
When Jake's mum suggested that Jimmy's exit may have been to do with viewers thinking he'd been bullying Jake, former X Factor star Jake was horrified.
"That annoys me because he was my best mate in there. When he left I found it harder. If that's how it came across, that he left because he was bullying me... not once did he bully me. Jimmy is one of my best mates. I can't wait to see him at the wrap party, have a laugh, get drunk and talk about the whole thing."
Jake finished runner-up on the show, behind Superbike champ Carl 'Foggy' Fogarty.
