During the weekend, Danny accused Mark's friends of attacking him at the Essex-leg of the event - in front of his teenage daughter Dani.
Mark has strongly denied any physical confrontation with the EastEnders actor, but now Danny's fiancée Jo has had a public pop at Mark's wife Michelle.
Yesterday, we told how Michelle had taken to Twitter and confirmed the start date for the new series of Our Girl, which sees her taking the lead role. But Jo has taken aim at this tweet.
She jibed: "It's official. I'm going to be promoting MY GIRL and the sh*t she witnessed. #yourtoof***ingstaged."
Jo also posted a message about her daughter, adding: "Hurt my daughter @Dani_MasDyer, I'll finish u off with pleasure. I have nothing to lose, maybe a fingernail."
Michelle has not responded to Jo's message, but some fans have been quick to slam her for bringing the former Coronation Street star into the row. One hit back: "Michelle wasn't even there, how is it anything to do with her?!"
Softening a little, Jo replied to one follower: "To be fair, you're right, seems like a nice girl. She weren't there. My daughter is a nice girl too that's the shame."
Reports of a bust-up came after a source told The Mirror: "It was EastEnders vs TOWIE, everything kicked off and security had to step in to break it up."
Mark's rep has no comment to make on Jo's tweet. Reveal has contacted Danny and Michelle's reps.
