Newly engaged “Bachelorette” Emily Maynard and fiancé Jef Holm carried on their made-for-TV romance at Abe & Arthur’s Tuesday night. Maynard was seen fork-feeding Holm chocolate cake for his 28th birthday and dropped a chunk into his lap, says a spy. Friends toasted them with, “Welcome to the family!” One diner said, “It looked like a full-fledged wedding rehearsal dinner.” Given the show’s poor record of couples who stay together, we’ll wait to see if they’ll make it to the real vows.
