Lydia and her on-off boyfriend became inseparable after being reunited on screen earlier this year, until his recent behaviour threatened their relationship - and his part in the show.
It was revealed earlier this week that singer Arg has been suspended from TOWIE for his partying ways.
And, now, The Sun reports that Arg was taken out of the show after testing positive for cocaine.
A source told the paper: "He has been doing really well, but unfortunately, he failed a test for cocaine.
"So they had no choice but to suspend him."
Arg has not commented on the allegations, although he did attempt to apologise to his fans for his suspension, saying: "For the 1st time in over 4 years I will not feature in an episode of #TOWIE. Don't worry I'll be back soon! Enjoy tonight's show guys, sorry x."
Meanwhile, Lydia has kept a dignified silence on the matter, but seemed determined to put the whole thing behind her on Friday night (31 October) as she celebrated Halloween with her sister Georgia.
Wearing black wigs and with bloodied faces, the Bright sisters looked dressed to kill - literally!
Lydia's sister Georgia has previously made no secret of the fact that she's no fan of 'Arg' and his behaviour.
Although Lydia recently admitted she's still in love with Arg, she also told him he has to clean up his act if he wants her to stick around...
Can a leopard change his spots? Only time will tell...
