Runaway Bridesmaid: Where in the world is Samantha Kluge? That was the question hanging on everyone’s lips — not least of all Liz Cohen’s — at Cohen’s much-hyped nuptials in soggy Palm Beach this past weekend. Kluge, as nearly everyone by now knows, was among Cohen’s 14 bridesmaids (joining the glossy ranks of Fernanda Niven, Rachel Peters, Ginny Bond Donahue and Alexandra Von Furstenberg). But she never showed up. “Samantha had to take care of herself,” her mother, Yolanda Kluge Mann, is said to have cryptically told people. Others wondered whether Kluge’s absence had anything to do with an ongoing feud between her and Von Furstenberg.
