Initially his in-house BFF Gemma wasn't Jonathan's first choice to be crowned this series' winner, with the Keeping Up With The Kardashians star backing Scotty T instead.
However, after seeing how much he means to Gemma in a hilarious video, he's now rooting for the TOWIE star to go all the way...
Taking to Twitter, Jonathan shared a video originally posted by Gemma's Twitter account. The footage shows Gemma reacting to news that Jonathan hadn't walked from the CBB house - even though he did go on to do so eventually.
Jonathan had been in talks with Big Brother to go, after beginning to feel claustrophobic, but he was persuaded to stay for a few more days. On seeing him walk out of the diary room, Gemma interrupts David Gest asking: "Is he back?"
She then jumps to her feet screaming Jonathan's name, before running up to meet him. Cute, right?
The clip clearly tugged at Jonathan's heartstrings and alongside it he tweeted: "This is awesome...nice to be missed!! I changed my mind on who I hope wins #cbb Hope Gemma wins it! @missgemcollins."
Throughout his time in the house, Jonathan struck up a close friendship with the G.C and has said, since leaving, that he is hoping to visit her in Essex in the future.
"Gemma's great," he said. "I had a great time with her, she's a funny girl, and we laughed a lot. I have a lot of friends all over the world and when I come to the UK, I will definitely call Gemma and visit Essex and hit the town."
When asked if he thought Gemma was using him to meet Kim Kardashian and her sisters, Jonathan didn't seem too phased. He replied: "I don't care, we had fun. I'm using her for the fun."
However, he has since said he won't be inviting Gemma to New York...
"Omg, is she gonna be attached to my hip?" He said. "I live in New York and it's freezing so if she comes over I'll be sending her straight back to London. I'll see her when I come over here. We can go chow down."
Jonathan was the first housemate to walk this series. Explaining the reasons behind his exit, Jonathan said he had continued to feel claustrophobic and the atmosphere had changed. He claimed the house wasn't as fun as it had been at the start.
