Natalie Cassidy father Charles has died aged 84.
The 38-year-old actress has taken to Instagram to announce that her dad passed away last month - which is why she's been absent from social media over recent weeks.
Natalie - who is best known for playing Sonia Fowler in 'EastEnders' - wrote on the photo-sharing platform: "I've been very quiet the last few weeks. I lost my precious daddy three weeks ago today. I wasn't really going to do this post, but I felt I can't come on here and be a k*** without letting everyone know that my life has changed.
"He was my whole world and I'm not sure what I'm going to do without him. All I know is my family, friends and work will make it easier. I cannot believe how lucky I am to have such wonderful people in my life.
"It really is at these times you realise how important relationships are and company and friendship and love is so important. Losing anyone is hard. The NEVER seeing someone again is cruel.
"But it's part of life. And we go on and have our memories. Charles William Cassidy 1937-2021. The best dad and grandad in the world. We miss you so much but we have each other because of you. (sic)"
Natalie subsequently received supportive messages from some of her former co-stars, including Jacqueline Jossa.
In response to Natalie's post, Jacqueline wrote on Instagram: "Sorry to hear that beautiful girl, love to you and your family. Lots of love (sic)"
Meanwhile, Scarlett Moffatt simply left a string of heart emojis beneath Natalie's emotional message.
