The actresses joined the likes of Stephanie Davis and Steven Roberts for upcoming episodes taking place on location at Abersoch, Wales.
The Channel 4 soap previously aired special Abersoch episodes last June, which introduced Tilly (Lucy Dixon), Jono (Dylan Llewellyn) and Maddie (Scarlett Bowman).
"Off we go again, tanned up & ready to go!!!," wrote Lucy Dixon.
She added: "[Stephanie Davis] catching some rays in-between takes :)."
The special episodes will air on Channel 4 later this summer.
Hollyoaks actress Montana Manning revealed yesterday that she has officially left the soap.
