Our "Extra" hosts got into the Halloween spirit today at Universal Studios Hollywood!
Even better, Mario's son Dominic and daughter Gia were there, too.
Mario and his mini-me Dominic dressed up as the King, Elvis!
Charissa and Gia proved "Diamonds Are a Girl's Best Friend" in matching pink Marilyn Monroe gowns and blonde wigs.
Meanwhile, Tracey stunned in a sparkly red Diana Ross dress!
