Jon Gosselin: Sock it Tumi

More proof that Jon & Kate may be minus each other -- maybe.

Our spies told us Jon was in a Tumi luggage store yesterday with two chicks -- "one older, the other youngish." The store is in a mall in Hackensack, New Jersey.

We spoke with a store rep, and it's true. The older chick plunked down $595 for a handbag. And, even worse than infidelity, that was the sale price!
