A mixed-race couple in Britain for the second time find themselves parents of twin girls -- one born with light skin and one with dark skin.

Miya was born with dark skin like her father, Dean Durrant, while Leah was born with white skin like her mother, Alison Spooner, 27, the Sun reported Wednesday.

Their twin daughters born seven years earlier also have different skin tones -- Lauren with white skin and red hair and Hayleigh with black hair and dark skin, the Sun reported.

"We didn't think it was even possible when we had Lauren and Hayleigh - and it didn't cross our minds that it could happen again. But we are just delighted that it has," Durrant said of his latest daughters, born Nov. 13 at Frimley Park Hospital in Surrey.
