The duo, who played Tiffany and Grant Mitchell in the BBC soap, reminisced on their time working together during an appearance on ITV's Loose Women.
Ross Kemp and Martine McCutcheon were reunited on Loose Women
Recalling her fond memories from her time on the show, Martine said: "For me it's some of the best times ever. There was a code between us, and we had each other's back. I was so young, I was 18, Ross watched me grow up. It was such an intense time."
Ross added: "You spend more time there with your fake family than you do with your real family and that's why some of the acting is so natural and so immediate because really, you have an alternative family."
The British stars' lives have gone in different directions since leaving the show, and while Martine is currently working as a panellist on Loose Women, Ross has recently returned from Libya where he has been filming his Extreme World documentary series.

However he did make a return to the soap in the lead up to his on-screen mother Peggy Mitchell's death earlier in the year, and admitted he felt more pressure this time around.
"When you're young and you first join there's not much expectation on you because you're young," Ross said. "At that age you're full of beans and you think the world is going to be your lobster. When you get older there's a fear of failing."
