Anthony, who plays Pam Hobsworth - aka Auntie Pam - will arrive back on the cobbles to visit the Websters.
Kevin then asks her to help him with his and Molly's baby Jack, according to the show's official website.
Pam was last seen on the Street with Kevin's dad Bill (Peter Armitage) last September, when the couple announced their engagement. Pam subsequently refused to let Kevin attend the wedding, with the stress of the situation resulting in Bill suffering a heart attack.
Anthony's Coronation Street scenes will air on ITV in April.
