The Sims siblings rose to fame on TOWIE and they’ve had plenty of their nearest and dearest relatives appear alongside them over the years; from their beloved Nanny Linda to Chloe’s daughter Madison and their cousins Frankie Essex and Joey Essex.
But despite the Sims being one of the most popular families in Essex, Chloe, Demi and Frankie usually keep their parents out of the public eye.
However, every so often they will share a cute throwback pic or a family selfie that features the mysterious parents, and Frankie did just that on her Instagram story recently.
The middle Sims sister posted a picture of her mum entering a coffee shop as they celebrated her birthday with Demi and their cousin Frankie. The post was captioned, "Happy birthday mummy."
The last time Frankie's mum was seen on her social media was last February when Frankie shared a mirror selfie of herself and her mum with two emojis showing how just much she means to her "❤️🌎"
The Sims siblings all share the same dad, Tony, however eldest sister Chloe has a different mum to her sisters and brother.
Frankie previously gave fans a rare glimpse of her mum on her social media account back in August 2022, referring to Mumma Sims as her 'twin.'
Way back in March 2022, Frankie posed with her mum as they spent the evening in Eastbourne during a getaway.
The TikTok clip, which was captioned, “Night away with Mumma,” showed the mother and daughter duo enjoying dinner together before returning to their hotel.
The reality star’s followers were loving their first look at her mum and flooded the comments section with compliments.
One wrote, “Omg why have I never seen her she’s gorg,” while another added, “Your mum is beautiful xx.”
A third commented, “Beautiful ladies ❤️.”
Do Chloe, Demi and Frankie Sims have the same parents?
Demi and Frankie Sims do, but Chloe is their half sister: they have the same dad, Tony, but different mothers.
Chloe Sims' mother walked out when she was just a toddler.
She explained, “I don’t know my birth mum. I’ve no memory of her at all. I think it was because of her age - she was only 19 when she had me.
“She emailed me about two years ago when I first started on TOWIE, but I didn’t reply. It was 27 years too late and I was a little bit over it by then. I’ve no desire to meet her or know her. I find it strange she’d wait that long to speak to her child."
Chloe continued, “In the email she didn’t even mention Madison and she talked about herself more, so I don’t know what we’d have in common.
“My dad’s offered to help find her and every time I’ve said no. I don’t think about her.”
