Lindsay Ellingson -- one of the seemingly few Victoria's Secret Angels not to have dated ­Leonardo DiCaprio -- is engaged. Her boyfriend, medical equipment sales rep Sean Clayton, popped the question at his parents' home in Ohio over Thanksgiving, sources told Page Six. Together for six years, the pair was spotted at a CBS screening Tuesday night of the network's Victoria's Secret Fashion Show special at Highline Stages. We hear the wedding will be in June in South Carolina.
