But what brings her back to the village? And will Juliet be pleased to see her mum?
Having forgotten that it's Sid's birthday tomorrow, Juliet and Peri make out to Courtney - who reminds them - that they have planned a surprise party for him.
Later, whilst the couple are preparing for the party and setting up at the Salon De The, Peri notices a text from Juliet’s mum on her phone and meets Donna Marie in village. She asks Peri for her help in proving to Juliet that she's changed and is going through rehab.
When Sid turns up at the Salon De The, he thanks the girls for the party but tells them that Tom is already throwing him one.
However, it's not long before Donna Marie slips back into her usual selfish ways and Romeo makes the decision to never forgive her for the pain she caused him and Juliet during their childhood.
As Donna Marie vows to stay in the village, Juliet has to decide whether she wants her mum back in her life or not.
