Susanna Reid was forced to apologise today live on Good Morning Britain after being corrected by a guest.
Diana Parkes, the mother of Joanna, who was killed by Robert Brown in 2010, appeared on the ITV breakfast show today to discuss the fact that Robert could be getting early release from prison as soon as next year.
However, as the interview began, Susanna - who was hosting alongside Ed Balls today welcomed her to the show virtually as she said: "Joanna's mother Diana Parkes is in the Isle of Wight. Oh Diana, I'm so sorry, my heart goes out to you."
However, Diana was quick to jump in, telling them: "Isle of Man, Isle of Man."
"Isle of Man, sorry! I beg your pardon," Susanna then went on to say, sending an apology for her mistake.
Diana now looks after her grandchildren - who had to hear their mother's horrifying death - and she previously said how much they have all relied on one another to process their extreme grief after Joanna's tragic death.
"I was always there for them, even at night. When, in the first few years, they woke up feeling sad, they knew they could come to my bed and get a cuddle. My husband moved into another room because he knew I had to be there for them," she said last year.
Last year, Diana appeared on Lorraine where she shared how "frightened" she was for his potential release.
She said: "As we're approaching his release, it is a total nightmare. We're frightened, not just for our family, but for the public in general. You know, he committed a horrendous crime... hitting my daughter over the head with a claw hammer 14 times, causing 37 injuries to her head whilst her children could hear it happening. It's my family who need support, I'm fine and I've lived my life. In a way, I wish he'd kill me because then they'll all be safe because he'd definitely be put away for good then."
Diana's grandchildren are now in their 20s and she is immensely proud of them.
"I'm so proud of them, they've grown to be two of the most loveliest people, they're 22 and 21 now and finishing their degrees at university. They helped me amazingly, I had a purpose in life to look after them," she added.
