Unfortunately, there's no publicly available information confirming that Emily Compagno is engaged. While she's a prominent public figure, she's maintained a significant degree of privacy regarding her personal life, including her relationship status. Many sources speculate about her relationships, but without official confirmation from Compagno herself or a credible news outlet, any such reports remain unsubstantiated.
Therefore, the answer to "Who is Emily Compagno engaged to?" is currently unknown. Her private life is, understandably, her own, and we should respect her choice to keep her relationship status confidential.
