The Cheshire-set drama will feature a storyline that sees the newcomers hoping to adopt Tom Cunningham and Peri Lomax’s baby.
Talking about the storyline, a Hollyoaks spokesman said: “As the summer continues, Tom wanders down a dark path to deal with the prospect of handing his baby to another couple.
“Meanwhile Peri is still determined to give baby Cunningham-Lomax a ‘better life’ away from Hollyoaks and their dysfunctional families.
“Both couples face a difficult path ahead.”
Adele said she was 'over the moon to be joining the show' and Ben said he was 'extremely chuffed to be joining the Hollyoaks team'.
