The animated show has told the story of Peppa, who lives with Daddy Pig, Mummy Pig, and her little brother George for more than two decades.
Mummy Pig has been portrayed by actress and comedian Morwenna Banks, while Amelia Bea Smith has been the voice of Peppa Pig since 2020.
The voice of the character of Mummy Pig told ITV’s Good Morning Britain: “I’m excited to share that our family is getting even bigger because we’re having another baby.
Earlier the series had teased the arrival of the new baby on social media, with a video of Mummy Pig remembering having a baby – including the crying.
Peppa Pig first aired in 2004 on Channel 5 Milkshake and Nick Jr, and is now available in more than 180 territories along with being broadcast in over 40 languages.
