Tia and Tamera Turn 34: How They've Grown Up in Hollywood (PHOTOS)
The identical twins turn 34 today, and Celebuzz has compiled a very special birthday gallery to show how the two have changed over the years.
And for those who can't get enough of the sister act, we even have a little Tia and Tamera trivia...
Sister, Sister was developed specifically for the twins. They landed a deal after a producer saw them on the set of Full House. Their brother Tahj Mowry made regular appearances on the show, and they often accompanied him to the set.
The premise of the show was simple -- they played twin sisters who were separated at birth and reunited after a chance encounter. Hilarity ensued as the they took on topical issues of the day, such as teen angst, sibling rivalry and body image issues.
The two now appear on the Style network reality show Tia & Tamera. Its first season focused on Tia's pregnancy and Tamera's wedding plans. This season, Tamera got the happy news that she's expecting a baby.
The two are super-close. In fact, in a recent interview with Celebuzz, Tia shockingly revealed that she'd actually try her sister's breast milk! Watch the video below:
