Things are almost incestuous on the Jersey Shore now!

Joan, Deena’s sister, was seen in the first episode of Jersey Shore season 5. But now she’s a point of interest again, because Mike’s older brother (Frankie Stylze Sorrentino) went on a date with Joanie.

A cursory look over Deena’s twitter, official website, and Wikipedia pages has produced no results on Joanie Cortese. Meanwhile, a search for Frankie Sorrentino yields information like how much he loves “Sick Bikini Girls” and “Official clothing.”

We have seen Mike trash talk Joanie, but be nice to her on the phone. Not cool. Since Mike admittedly likes torturing Deena about this, we’ll likely hear more about the dating saga of these siblings on Jersey Shore next week.
