Jon Gosselin and his latest girlfriend Ellen Ross walked the mean streets of Manhattan Friday, and at Breaking Celebrity News, we couldn’t help but notice that Jon has gotten more than a little plump.

Ironically, we found Jon’s ex-wife Kate – looks firm and fabulous -- carrying a tote bag covered with the words NEW YORK just this morning as she shopped near her home in PA.

Jon and Ellen strolled hand-in-hand during their visit to the Big Apple.  The two began dating earlier this year.  Maybe they dine out a lot?
