The popular TOWIE star told the Mirror, "Our first date was amazing. I'm very happy. Look at her, she's beautiful."
News of the romance won't come as a big surprise to the reality show's viewers, who spent weeks watching the pair cosying up in the jungle.
Beauty queen Amy made a big impression on Joey from the start.
"When I first saw Amy, I thought 'salty potato', then I really looked at her and was like 'woah, she's beautiful'. But then I got to know her and I realised she's actually a proper nice girl," he said after leaving the show.
Joey and Amy were both voted out of the jungle on Friday in a shock double eviction, and have been inseparable ever since.
Since then, Joey, 23, has shared a photo of himself and Amy sitting down to a feast of pizza and chips at the Palazzo Versace Hotel, and sunbathing together, captioned, "Chilling by the pool. Versace Versace Versace."
He has even introduced 21-year-old Amy to his father Donald, who was initially convinced Joey would reconcile with his ex-fiancée Sam Faiers.
Joey and Sam split up before he went on I'm A Celebrity, and she was rumoured to be entering the camp as a shock guest, although that proved to be false.
Bookies are now offering odds on 10-1 that Joey and Amy will end up marrying like former jungle couple Katie Price and Peter Andre.
