The Sweet Valley series was hugely popular for many teens growing up.
Chronicling the entire lives of the Wakefield twins from childhood to adulthood, creator Francine Pascal produced a number of series and spin-offs, from Sweet Valley Kids, to Sweet Valley High, and Sweet Valley University.
And who could forget the iconic '90s TV series, starring Brittany and Cynthia Daniel as the golden-haired Wakefield twins.
In case you've forgotten, The Wakefield twins were often described as "slim, five-foot-six, with shoulder-length, sun-streaked blond hair, flashing blue-green eyes (the exact colour of the Californian ocean!!), and of course, perfect tan skin."
