Gemma Atkinson is expecting her second child with partner Gorka Marquez.
The former Hollyoaks star, who met her professional dancer boyfriend on Strictly, joked that her bump had become "impossible to hide".
She also revealed that she would be expecting a baby boy - her first son after welcoming daughter Mia in 2019.
In a candid black and white photo of herself in a pair of tracksuit bottoms and a vest top, Gemma was pictured gazing down at her bump with a small smile.
She tweeted: "Impossible to hide my belly any longer. I’ve officially 'popped.'
"Our baby boy will be joining our family later this year.
"We feel so incredibly blessed and Grateful to be on this journey again. Mia is absolutely thrilled! Although we may need to do some negotiating on names, as so far she’s adamant he’s going to be called Barbie."
Gorka reshared the post, tagging it with a simple "#blessed" comment.
Their friends were quick to share their congratulations, with Giovanni Pernice writing: "Congratulation !!! The best family and def the best parents."
While Mollie King wrote: "Ahhh such lovely news you guys! So happy for you!!"
"Ahhhhhh so happy for you lovely xx," Candice Brown gushed.
While Amy Dowden wrote: "Soooooooooooo happy for such a beautiful family."
John Whaite added: "Aaaahh what lovely news. Congratulations."
Gemma's pregnancy is likely the reason Gorka pulled out of the Strictly live tour this year as he didn't want to spend time away from his family.
Fans were left gutted after discovering that Helen Skelton wouldn't be performing with Gorka. Instead, she's dancing with Kai Widdrington after the tour kicked off on Friday.
Gemma last year opened up about her "traumatic birth" with daughter Mia - but insisted that it hadn't put her off having another child.
She said on Steph's Packed Lunch last year: "I’m at the stage where I want a sister or bother for Mia. The first few months of Mia’s life, I kept saying to my partner, Gorka, I’m not going through that again. I’ve now come of it and I feel I could."
In the candid post in 2019, Gemma explained that health professionals were forced to take action when Mia’s heart rate began to drop while still in the womb - and later took action after Gemma started haemorrhaging huge amounts of blood.
“This picture was taken when Mia was 30hrs old. The weary smile on my face doesn’t quite portray how happy I was inside as 30hrs earlier, things could have gone very differently,” Gemma wrote.
“Mia was a tiny baby, 4lb 10. With that in mind the midwife was concerned she wouldn’t be strong enough to open my cervix.
“My water broke on a tues & we gave her the benefit of the doubt but by the Wednesday evening despite her being in the perfect place & so low down, she still hadn’t managed it.
“The decision was made to induce me to help her along but she disliked that even more. With every contraction her heart rate dropped. On the 3rd one midwife Katie who was taking care of me at the time pressed the panic alarm & within 15 mins I was rushed out, prepped & delivered Mia via an emergency C section.
“It wasn’t what I’d planned but thanks to my hypnobirthing despite the madness & panic, I was able to calmly keep my breathing technique & accept whatever is best for Mia just do it!”
She continued: “2hrs later I was alone with Gorks & Mia blissfully happy in a ward when I suddenly felt extremely unwell. Gorka got a doctor and she took 1 look at me & again pressed the panic button. I was having a hemorrhage. A big one & I lost a lot of blood.
“I don’t remember much other than having around 9 doctors in the room, some injecting me, hooking me to drips, physically pulling clots out of me & one comforting Gorks who was beside himself in the corner.
“I woke in another room with Gorks & my family there, Mia sleeping soundly & a lovely midwife named Di who was checking my notes. The trauma was over & thanks to our NHS & incredible hospital staff we were ok.
“I’m fully aware for some people it’s a different outcome & I feel incredibly lucky that me & Mia are healthy & healed. My mum moved in with me while Gorks was away & has been incredible! If I can be half the mum she is to me I’ll be happy!” she said.
