Lady Gaga's bad- ass alter ego/ apparant old flame. He appears in her music video for "You and I" and even attended the 2011 VMA's in her absence. During the awards, he performed her single "You and I" and accepted the Best Female Video, and Best Video With a Message on his woman's behalf.

He even tried to make a move on the "INCOMPERABLE BRITNEY SPEARS!" but unfortunately was unsuccesful...

A man of mystery, but certainly not a stranger to the stage, much about Jo remains unknown. He was on the cover of Japan's Vogue Hommes in September, 2011 and stated that he "had never had his picture taken before".

Jo is loud, rude, and obnoxious, but he truly cares for his girl, Lady Gaga. He has attracted the attention of countless girls across the country and even some from men.

He's a greaser with great pipes (courtesy of Gaga herself?) and some mad hip movements.

Person 1: Hey man did you see Lady Gaga on the VMA's last night?!

Person 2: Dude I don't know what you're talking about. Gaga wasn't there- Jo Calderone took her place. He killed it!!"

Person 1: OH. so THATS who that random greaser was!
