Their ups and downs have been documented on camera since TOWIE began in 2010.

And it seems Lydia Bright just can't stay away from her on/off boyfriend James 'Arg' Argent since the former lovebirds are alleged to have hooked up during TOWIE filming in Marbella earlier this week.

The 26-year-old blonde, who last split from Arg in April, reportedly 'deeply regrets' leading him on and has no intention of getting back together with her co-star.

A source told The Sun: 'Lydia can’t believe she fell for Arg’s charms once again.

Lydia said their 'difficult' relationship has made her a stronger person, adding that she does not see herself getting back with James in the future.

She said: 'For me there is no going back, we have been through a lot over the years. but I reached my limit the evening we broke up.'

Lydia ended things with her long-term boyfriend in May after he allegedly relapsed into his cocaine habit.

Arg's party lifestyle had been a source of contention over the years, with most of their rows revolving around him keeping secrets from her and slipping back into his bad ways.
