Chloe Lang was born in November 14, 2001 in Connecticut her Parent's name is Tina Lang that is he mother and I do not know about her father. And Julianna was born in May 26, 1991 in Irvington New York.
It does say who Julianna's parents names are because maybe she no popular enough or maybe she does not want people to know about her parents her siblings name is Alex Mauriello that is her sister.
Lazy Town used to be a show on Nick Jr. Then it was on PBS Kids Sprout and also read it was on other channels like CBeebies, CBBC, BBC, Universal Kids, Jetix, Disney Channel, France 3,YTV, Super RTL, Stöð 2, RÚV, Discovery Kids, Vrak, Treehouse TV, RTP2, Vrak, Viacom International Media Networks Europe and Turner Broadcasting System Europe.
So I think first Mauriello played Stephanie first because she is older then Chloe Lang the years later Chloe Lang played Stephanie. Julianna is 5 feet and five inches and Chloe Lang is 5 feet 2 inches that I read.
