Bachelorette Ashley Hebert and fiancé J.P.Rosenbaum enjoyed a PDA-filled double date with J.P.’s brother Roy and his girlfriend, Andrea Pope, at New York City eatery Zio. The foursome noshed on saffron risotto cakes, a pan-seared grouper dish and sheep’s milk ricotta dumplings. “Ashley and J.P. were so lovey-dovey with one another,” says an onlooker. “From the moment he got her out of the cab, he couldn’t get his hands off her and they were kissing nonstop.” As the meal ended, J.P. fed his ladylove her dessert.
