Darren Day and Donna Air are to appear in a 'Hollyoaks' late night special.
The duo will feature in upcoming one-off episode 'Hollyoaks: King Of Hearts' as notorious bad boy Danny Houston and his drug runner Sophia.
While Darren recently joined the cast of the Channel 4 soap, this is Donna's first appearance.
She said: "I am thrilled to join the cast of 'Hollyoaks' for the late night special. The cast and crew have been so welcoming, and I'm excited to be part of such a hit show. The storyline is great fun and I love playing the role of Sophia, she's brilliant."
The pair will be involved in a sensational storyline, which will see Kathleen McQueen (Alison Burrows) threaten to shop her own daughter Theresa (Jorgie Porter) to the police after finding out she was responsible for the murder of Calvin Valentine (Ricky Whittle), who is the father of her baby.
In a bid to conjure up the £2,000 Kathleen is demanding from the McQueens in return for her silence, the family team up with Rhys and Gilly - played by Andy Moss and Anthony Quinlan - to attempt to con Danny out of the cash and kidnap Sophia.
However, the plot thickens when Jacqui McQueen (Claire Cooper) finds herself surrounded by Danny's gang, who force her to strip at knife point.
A 'Hollyoaks' spokesperson said: "Trouble is never far from the Hollyoaks village especially when the McQueen's are involved. Expect double crossing, dangerous liaisons and dastardly consequences.
"The events that unfold will affect the lives of Chester's favourites forever."
'Hollyoaks: King Of Hearts' is due to air on Channel 4 on December 16.
