Hand In Hand
Vienna and the "Greek" actor were dancing with each other -- hand-in-hand -- at the Reality Cares CHOC Children's Hospital Prom on Saturday night.
As we previously reported, sources close to the production of "The Bachelor" tell us Jake eventually pulled the plug on the relationship with Vienna because he thought she was "stepping out" with Gregory on the side.
But Vienna claims she never cheated on Jake -- and her stepmom claims the split was all Jake's fault ... because he's a fame-whoring fraud.
The drama never ends ...
