Gemma Atkinson accidentally flashed her thong while giving an update to her fans on her pregnancy.
The former Hollyoaks star has been keeping her followers up to date along her pregnancy journey, but showed off a little more than intended.
In the video, Gemma, 38, was showing off her growing bump by pulling down her grey leggings.
She was also wearing a cropped T-shirt and trainers, with her blonde hair tied up.
But as she was giving fans a closer look at her tummy, Gemma accidentally flashed her thong.
The actress turned influencer shrieked as she realised what she had done.
"Oh! I'm showing me thong!" she squealed as she immediately noticed what had happened.
Despite the wardrobe malfunction, Gemma shared the moment with her 1.8 million followers, who were happy to see the pregnancy update.
In the video, Gemma explained how she was finding the experience.
"There he is, growing away. Cooking away nicely. As is my boobs and bum. My bum's just flat now. But yeah, cooking away nicely," she said.
Gemma is expecting her second child with fiancé and Strictly Come Dancing star, Gorka Márquez.
The couple met on the show and already have daughter Mia, who is three.
Following the arrival of their daughter, Gemma revealed she had a difficult childbirth and almost died as she started haemorrhaging in labour and her daughter's heart rate began to drop.
Approaching her second birth, Gemma has said she is riddled with anxieties about giving birth again.
She has shared her worries with fans, saying: "We're getting everything mentally in place. Physically, I can do this but mentally, it's like hitting a wall in a workout. I need to just push through."
The concerns have led the TV star to opt for a private midwife.
Taking to Instagram, she wrote: "I love our NHS but I know how stretched they are and with the strikes still happening I felt uneasy at the thought of history repeating itself with my pregnancy and not enough staff to help. (BTW, I fully support their reasons for striking and they should absolutely be paid a hell of a lot more for what they do!)
"Our baby will be born at an NHS hospital but my pre and post care will be done by Rach. Last time I was told Mia was going to be a big baby and she was absolutely tiny so this time I felt I needed and wanted monitoring more closely.
"I'll be having a lot more scans this time keeping a close eye on baby's size (so far everything for baby and me results wise are spot on and as expected)."
