A woman who had two sets of twins only eight months apart has become a world record holder.
Tracy McKeown, from Uddingston, Lanarkshire, England, gave birth to the second set of twins only 48 hours after being told she was pregnant again.
Guinness World Records say Ms McKeown has set the record for giving birth to two sets of twins within the shortest time.
Ms McKeown and partner Dennis Loney, already had 10-year-old Mark and twin babies Ryan and Denise, when Stephen and Natalie Ann were born.
