No, this is not a Halloween prank. Gia Giudice, the 13-year-old daughter of "Real Housewives of New Jersey" star and soon-to-be guest of Club Fed Teresa Giudice, has debuted the first music video by her new girl group 3KT today, in which they shake and shimmy in teensy outfits to their cover of Britney Spears' "Circus."

Montville Township's Gia is joined by 16-year-old Alexa Maetta, who was part of her Project T.R.U.E. dance crew, and Cristianna Cardinale, 14, and the group is represented by Xist Talent, the New Jersey-based management group that Gia has been working with since 2007. Xist owner Maria DeSantis has appeared on previous episodes of "Real Housewives of New Jersey" as Teresa and Gia pursued various acting, modeling and dancing opportunities over the years.

To wit:

RadarOnline.com is reporting that Teresa — who reports to prison Jan. 5, owes millions and has all three of her houses on the market — paid $10,000 (the girls' parents reportedly contributed as well) for the production.
