Former Coronation Street star Sanderson has joined the soap as Maxine Minniver, sister to Mitzeee, and Porter predicted a bright future for her in the village.
"I absolutely love Nikki. I think she's so grounded, normal and down-to-earth, a really lovely girl. She'll be a great little addition to us all. She's going to be really fun and fit in really well I think," she told What's on TV.
Porter, who plays Theresa McQueen, also hinted at Theresa and Maxine's relationship on-screen.
"Theresa used to absolutely be in awe of Mitzeee so hopefully she'll be in awe of Maxine too. Because sometimes girls do that, don't they - have girl crushes," she explained.
Sanderson is due to appear in Chester from next week.
