A gender reveal for Peppa Pig's new baby sibling was staged at Battersea Power Station on Friday, 25 April.
The animated show, which tells the story of Peppa, who lives with Daddy Pig, Mummy Pig, and her little brother George, announced the pregnancy in February.
On Friday, the power station chimneys were lit up to show whether Mummy Pig is expecting a boy or a girl.
Viewers can expect to see the new baby on screen in the autumn.
A gender reveal episode will air on YouTube on 3 May as part of the Peppa Pig Tales series.
