Billie Faiers has revealed she predicted her younger sister Sam's pregnancy and "just knew" she was expecting because she "seemed different".
The Family Diaries star, 32, said she 'screamed the house down' when Sam told her she was having a third child with her long-term boyfriend Paul Knightley.
In an interview with OK! Magazine, Billie, 31, spoke of how she had a "gut instinct" her sibling was going to have a baby as well as hitting back at claims that she and husband Greg Shepherd have been rowing with neighbours over the build of their £1.4million dream Essex home.
Sam announced her pregnancy in November, sharing a sweet snap of her son Paul, six, and daughter Rosie, four, kissing her baby bump.
Speaking of her sister's news, Billie gushed: "I cannot wait to have another baby in the family, it's been so long since the last time as, obviously, Rosie was our last so we are over the moon for them.
"I actually had this gut sister instinct that she was pregnant before she told me, I just knew. I looked at her and she seemed different.
"Then, that afternoon she told me I literally screamed the house down, it was the best surprise, my mum is so happy she’ll have five grandchildren."
Elsewhere in the interview, former TOWIE star Billie talked about the build of her dream home, and revealed the family hope to move in a few months - more than a year after work on the extensive renovation plans started.
However, the reality star, who is proud mum to Nelly, seven, and Arthur, five, insisted she wanted to 'set the record straight' as she slammed reports of rowing with her new neighbours.
Those living in the neighbourhood had originally opposed the couple's plans submitted at the time to demolish the house on the grounds and replace it with a five-bedroom mansion.
Billie said while they had a "few issues" when seeking permission, there has been "no complaints" since the couple got the green light for their extensive plans, which include a swimming pool, a 'man cave' and five bedrooms with en-suite bathrooms.
Billie went on to say how some of her new neighbours "have popped around to introduce themselves" with the family hoping to move into the property within the next few months, with builders currently plastering the walls.
Also in the interview, Greg, 37, discussed having a hair transplant. The reality star got the procedure in January after noticing he was going bald when he shaved his hair for charity.
The television personality said he first noticed his hair falling out after they got married in 2019 and he sees the transplant as a "week of discomfort" to have a thicker hairline for the "rest of your life".
Now set to star in an all new Family Diaries series, Billie revealed the show will follow them as they juggle family life with renovations and work.
The reality star said the second series will be "jam-packed" with "so much going on". Billie's sister Sam stepped back from filming Mummy Diaries in June last year after nine seasons.
Billie & Greg: The Family Diaries returns to ITVBe from 23 March at 9pm.
