James 'Arg' Argent and Lydia Bright reportedly spent a night together recently.
'The Only Way is Essex' stars have been seen rekindling their friendship on the latest series of the ITV2 reality show and while Lydia, 24, previously insisted she won't get back together with her ex, the pair are said to be romantically involved.
A source told the Daily Mirror newspaper: "Lyds was really adamant she didn't want to get back with Arg, but while they've been spending time together all their old feelings have come back.
"They're not officially an item again just yet, but Arg has been working hard to woo her and it's paying off."
Lydia and Arg, 26, called it quits after four years together in 2012 when Arg admitted he had cheated on her and the budding fashion designer - who recently returned to 'TOWIE' - is torn between her head and heart.
The insider explained: "Lydia still wants to be sure before they make any long-term commitments. She has reservations about their relationship, as do some of her friends and family. She doesn't want to look like a mug by taking him back after he admitted cheating on her.
"But she has realised she still has feelings for him, and since spending the night together she says she knows they are more than just friends."
