London, March 21: A British woman has given birth to the biggest ever baby girl, coming in at a whopping 5.67 kg (12lbs 8oz), reports Daily Mail.
Pictured here next to her cousin Thomas - who is actually younger than her - baby Libby, from Wigan, is twice the size of the average newborn.
The youngster, who has three older brothers, was born after a surprisingly short labour of just six hours.
Mum and dad Gemma and Ian Woods were over the moon to finally have a long-awaited daughter in their family but weren't quite expecting such a large baby.
Not only was it a relatively short labour, but brave mum Gemma, 28, had a natural birth and opted only for gas and air pain relief.
'I just couldn't believe it when the midwife told me the weight - I thought I was hearing things,' she told the Sunday Mirror.
'When she was two weeks old we took a photograph of her next to my nephew Thomas, who was born three weeks early.
'He weighted 3.09 kg (6lb 13oz) - and she absolutely dwarfed him.'
The heaviest baby ever born was in January 1979 when Anna Bates gave birth in Ohio to a boy that weighed 10.77 kg (23lb 12oz) but he died 11 hours later.
The heaviest surviving newborn was in Aversa, Italy, in September 1955 which weighed 22lb 8oz.
