Amy and Joey had a short fling after both completing a stint in the jungle for I’m A Celebrity Get Me Out Of Here last year but Amy denied the pair were together, days after Joey was quoted as saying they were an item.
Amy and Max were reportedly seen kissing in Vodka Revolutions earlier last week after The Wanted show in Brighton.
The model also tweeted pictures of The Wanted’s show at the London 02 and has been posting on her Instagram account pictures with Max.

Max, who used to be engaged to HELLO! Online blogger Michelle Keegan and also dated Lindsay Lohan, is on the final tour with The Wanted, who confirmed their split in January to pursue personal endeavours.
In a statement on their website, the band – Max George, Siva Kaneswaran, Jay McGuiness,Nathan Sykes and Tom Parker – said their forthcoming Word of Mouth tour would be "their last for a while", but insisted they would "continue on as The Wanted."
During her stint on the last season of I’m A Celeb… Amy was accused of not playing a fair game.
Speaking after her eviction, former model Annabel Giles said: "We keep finding little signs that it's not a level playing field and that Amy's playing a game. She carries a massive handbag with her which we all suspect she carries piles of cosmetics in."
