The wrestler coupled with Katie in the final few days of the show and they ended up in fourth place on Monday night's (11 July) live finale.
But earlier today, Adam, 24, suggested romance with Katie, 20, was off the cards when he tweeted: "Speaking of hashtags #100%Single."
Now, he's added one of his famous metaphors, which, given the timing after his single tweet, has everyone speculating…
He wrote: "It's like when you're eating a kebab after a night out & the first few bites taste good but then u realise that it really isn't nice at all!"

@AdamMaxted who Katie?— FRINDSEY FOR LIFE (@ABS699) July 15, 2016
Is it about Katie or not? Adam hasn't said anything, Katie hasn't said anything so honestly, we're a bit confused!
Adam did share a few Snapchat stories from last night's Love Island wrap party showing him and Katie looking rather cosy. One was even a close up of her bottom! Which makes things even more baffling.
C'mon Adam, what is going on?!
Adam and Katie finished fourth on Love Island and were the only couple in the final not to have made it official in the villa, but then again, they'd only just coupled up.
When model Katie entered the villa, she initially coupled with Sophie Gradon, but that ended when Sophie quit the show after fearing her relationship with eliminated islander Tom Powell could be jeopardised if she remained coupled with Katie.
Adam then made his move, telling Katie he was attracted to her and would like to couple up.
Katie agreed, and told him: "I just didn't want you to think you're the second option. I completely did not know who I was going to pick," said Katie. "I don't want you to think that because my first plan failed that I'm jumping to my second, because I genuinely said from the start that I liked you both. You do make me laugh, I find you very funny."
Things had seemed pretty positive for the pair, as they shared a few kisses, cuddled up and Katie even said she would visit Adam in Northern Ireland.
"We're getting on nice. I like the fact that he's such a chilled laid back guy. I'd go to Ireland and see him, definitely," she said. "I'm looking forward to getting to know him more because it still is early days, obviously. It's nice you can have someone in here you can have a little kiss with and a little cuddle."
They spent one night in the hideaway but didn't have sex because Adam didn't want to jeopardise his dream of starring in WWE in the US.
