Earlier this month, it was confirmed that former EastEnders star Collins would be joining the cast on the cobbles as new Rovers Return barmaid Stella.
The actress told ITV that she will begin filming on Monday (May 1), adding: "I'm very excited."
Asked if she would be channelling the spirit of former Walford character, superbitch Cindy Beale, Collins said: "No, [she won't be nasty].
"She's strong, she's feisty, she's funny. I don't think there'll be any murders for a while, put it this way!"
Collins also revealed that she is already friends with a number of Coronation Street cast members from her time on the rival soap.
"Helen Worth (Gail Platt) I know. In fact, I made the terrible mistake of calling her 'Gail' in make-up the other day, which was very embarrassing and I won't be doing that again!" she added.
Earlier this week, it was reported that Collins's character Stella will clash with Tracy Barlow when she arrives in Weatherfield in June.
