Billie Shepherd told her kids she was pregnant again by writing them an emotional letter.
The Mummy Diaries star, 32, is already mum to Arthur, eight and Nelly, five, who she shares with husband Greg.
The former TOWIE talent is now five-and-a-half months pregnant and recently shared the special moment her son and daughter found out there was going to be a new addition to the family.
After taking a test to confirm she was pregnant, Billie said: "We wrote a letter from the baby to Arthur and Nelly and put it by the front door.
"It said, ‘Dear Nelly and Arthur, you haven’t met me yet, but I’m in Mummy’s tummy. I’m going to be your brother or sister. I can’t wait to meet you.’
“Nelly read the letter and screamed and was crying – they were happy tears!", Billie told OK!
The blonde bombshell added that the emotional moment was going to be on ITV2's The Family Diaries, in which she chronicles parenthood with her hubby, Greg.
Billie, whose sister Sam recently had her third child, said the pregnancy came as a shock at first.
Explaining that she felt "a bit sicky" at a party, the mum-of-two went to buy a test, which 'surprisingly' turned out to be positive.
Billie and her brood were recently in Greece with showbiz pal Ferne McCann, who was celebrating her engagement to Lorrie Haines.
The reality regular showed off her beautiful bump after sparking rumours among her fans about the gender of her third child.
In a string of stunning snaps, Billie shared one in which she kisses Greg on a boat overlooking the sea.
Although the pic shows the Essex native sporting a simple white dress with bare feet, it was the caption that got fans talking.
Billie captioned the snap with two emojis, an anchor and a blue heart, which provoked many of Billie's followers into thinking she was having a boy.
While the 32-year-old is “happy and excited” to welcome the new addition to her family, Billie has admitted she is more nervous this time around.
She told New magazine: “I’m carrying really low and I feel like there’s a lot of pressure down there already. Although I’m not really big yet, I feel like if I’m on my feet for a certain amount of time, I need to sit down.”
Explaining how it feels different to her other pregnancies, Billie shared: “When I had Nelly I was in my early twenties, now I’m in my early thirties, so that could make a difference."
