Tia and Tamera Mowry
Twins seemed to be a popular theme on TV in the '90s and 2000s, and another famous set of child star twins is Tia and Tamera Mowry.
In their younger years, they co-starred in the show Sister, Sister. They would collaborate again in Twitches and its sequel later on. They authored four books in a series called Twintuition as adults, although each sister has also pursued individual projects.
