Martin has warned Ashley and Harvey about rival Celebrity Big Brother housemate Julie.
Speaking to the boys in the Garden today, Martin warned the youngsters not to get too caught up with Julie's bitching.
"I love Julie as much as you guys, but she will push it to the edge. She will speak her mind, she's already taking it onto the edge. Be careful of it," he told the duo.
Taking a chance to reveal his true feelings about Julie while she was talking to Big Brother in the Diary Room, Martin went on: "I laugh at Julie as much as you guys and she pushes it on you, but one step further and it doesn't look on you.
"Just think about it.
"I'm not happy with some of the things Julie's been saying, I think it's far too far. It's up to you guys, I'm just telling you how it is."
The former Eastenders actor continued: "Julie will come out of here and walk away, go back to her farm in Manchester, but you two have a long way to go, if you come out of here stained, it's not going to be good for you, I'm just telling you how it is."
He added: "Look after yourselves an think of the consequences before you say things."
