The reality TV stars – who have been dating on and off for more than three years – were enjoying a night out at Essex nightclub Nu Bar but things took a turn for the worse after Lydia drunkenly pecked a male friend on the cheek.

According to one witness, Arg “blew up” and the pair had a screaming match.

The onlooker told the Daily Star: “It was mayhem. Arg and Lydia were screaming at each other.

“They left in separate taxis. Lydia hooked up with a guy near the DJ box. She was getting really cosy with the guy, with his hands all over her.”

However, Arg and Lydia – who cut her foot during the night out – have played down the reports and insist everything is great between them.

Arg said: “It wasn’t really a row, I was just telling her I was worried about her being cut. That is what we were arguing about, just getting her plastered up.”

Lydia’s spokesperson added: “She tripped up inside Nu Bar and landed on some broken glass. Lydia wasn’t kissing anyone. The man is a mutual friend of her and James from school.

“James wanted Lydia to go to the office in the club and see to her leg with the first aid box and she got in a taxi to go home. She was just telling him that she was going home.”
