The TV stars were providing relief cover for Cat Deeley and Ben Shephard on Wednesday's edition of the ITV magazine show when Sharon Marshall, known as the Soaps Queen, arrived with all the latest gossip regarding the long-running BBC programme.‌The storyline in question regards Zack Hudson, the biological half-brother of Sharon Watts, and Vicki Fowler, who is the adoptive half-sister through of Sharon through Den Watts, meaning that there is no blood relation there.‌Sharon said: "So, Sharon’s back, she’s going to find out that her brother is sleeping with her sister. Messy, messy!" to which a shocked Sian interjected with: "Sorry, her brother is sleeping with her…” and Sharon simply said: "Yes."‌Sharon then explained: "It’s alright, it’s not a blood relation because Sharon was adopted by Dirty Den. So although her brother is sleeping with her sister, they aren’t actually biologically related.”It was then that the trio burst into laugher and Sharon appeared relieved that she had managed to explain the confusing situation and they moved onto the next item.‌Vicki is set to walk down the aisle to marry Ross Marshall on Wednesday night's episode and Zack (James Farrar) is the best man. But actress Alice Haig has said she thinks Vicki is trying to “put Zack behind her”.Alice said: ”She wants so much for it to be the perfect wedding and this is hanging over her, this dishonesty. “I think she feels like she can't fully embrace it,” she adds. As such, she turns to her friend and aunt Kathy Beale (Gillian Taylforth), the first person to know about the affair with Zack.Alice added: "She tells Kathy how guilty she's feeling and in a way that really helps because she kind of finds a bit more sense as to why all of this has happened. She realises that a part of what drew her to Zack was him being not linked to Joel.”‌Fans will remember the huge storyline concerning Ross’ son Joel (Max Murray), who went down a red-pill pipeline and brutally attacked Vicki, leaving her bleeding on the floor. Joel filmed the horrifying attack and posted it online. Eventually, Joel stood trial for his crimes, where Vicki had to relive her trauma all over again.Alice said she thought Vicki’s attraction to Zack was tied to “her regaining some kind of control over her life and her body after everything that happened with Joel”. But, ultimately, she loves Ross and wants to marry him.Article continues below“She has been saying from the beginning that she loves Ross and that she doesn't want to be with Zack,” Alice added. “Then her behaviour has said otherwise."This week when she has that realisation that actually it was never about Zack, and was instead about finding herself again and having something that wasn't connected to Joel, I think that has given her much more strength and much more resolve to refuse his offers.”Like this story?
