Coronation Street 's Kate Ford shared a sweet comment to her on-screen daughter Elle Mulvaney earlier this week. Elle, 19, took to Instagram to share a collection of snaps of herself from co-star Harriet Bibby's, who plays Summer Spellman, birthday night out over the weekend. The actress' 76.9K followers were quick to react to the snaps, captioned "til death do us party", to which co-star Kate, who plays her on-screen mother Tracy Barlow, led the comments.
