Casey Johnson was on the warpath in tonight's episode of E4's Stage School.
It followed another row between Casey and girlfriend Betsy-Blue English on last night's show.
The pair of former X Factor finalists are currently dating but appearing on the E4 reality series appears to be putting a strain on the relationship.
Each has accused the other of being jealous over their closeness to others, with yesterday Casey storming off in a huff after Betsy-Blue spent time with new guy Alex.
Alex and Betsy-Blue went glamping - with Megan Jossa - and it didn't leave Casey impressed when he found out.
But Betsy-Blue insisted her and Alex were just "making music together" and remarked: "If you played the guitar, maybe we could make music together but unfortunately not... are you jealous?"
She snapped: "You don't want other boys to look at me and I'm sick of it."
Casey insisted he wasn't jealous before doing a runner from the college.
This evening, Casey got (dubious) word from a 'source' that Betsy-Blue had supposedly been getting snuggly with Alex in the words.
Casey promptly confronted Betsy-Blue, who was with Alex preparing for a gig, and confessed: "I'm going to be honest with you yeah I'm annoyed with you hanging about with Alex all the time."
Betsy-Blue was left in tears by Casey's sudden appearance and told him: "It's not fair, I'm about to do my gig and I don't need it, I don't want to talk about it right-now, this is too much. I'm just really done with it right now."
Elsewhere on E4's Stage School yesterday, OJ decided to cool things off with Leah via a rap, which went as well as everyone expected it not to.
In tonight's show, he made a grand gesture to win back the girl of his dreams - Pia - but despite putting on a limo for her, she said it was 'too soon' for a reconciliation.
Meanwhile, Jamie had a shock announcement for Bonnie and Donna as he announced plans to LEAVE the school
E4's Stage School continues week nights at 7:30PM.
