What happened to Tia and Tamera Mowry??

Once the sitcom ended in 1999, (Sister, Sister) the girls, now 25, decided to hit the books. And, as if they weren't already inseparable, they took the same classes -- earning psychology degrees from California's Pepperdine University in May. In between, they kept a hand in acting with the Disney TV movie "Seventeen Again" in 2000 and the 2002 film "The Hot Chick". They're now mulling scripts, deciding which movie to do next. You can bet it will be a two-person job.
