The Sister Sister stars attended a signing for their new book Twintuition, which tells the story of tween twins Cassie and Caitlyn discovering that they have the ability to see things before they occur.
Chat show host and actress Tamera looked beautiful in a fitted black knee-length dress and white blazer jacket.
Tamera, who is expecting her second child with husband Adam Housley, is due to give birth in July.
Meanwhile, Tia looked ever so chic in a black jumpsuit with flared legs, and we're loving her super sleek hair.
Tia and Tamera gained fame on the 90s sitcom Sister Sister, and just two weeks ago, Marques Houston (who played Roger) and Tia reunited!
While Tia now holds the role of star and producer on Nickelodeon's hit series Instant Mum, Tamera is one of the hosts and producers on hit talk show The Real.
