Crystal Hefner, Hugh Hefner’s widow.Jason Kempin/Getty ImagesHugh Hefner, who died Wednesday evening at 91, is survived by his wife, Crystal Hefner.

Hugh has been linked romantically to many women, but he has had only three wives.

The pair married in 2012, when Crystal was 26 and Hugh was 86. However, their road to the altar wasn’t so smooth.

The pair became engaged in 2010 and were expected to wed in 2011, but Crystal famously backed out of the wedding five days before.

But despite the rocky start, Crystal and Hugh seemed happy together. Crystal could often be spotted in Hugh’s Instagram feed. Hugh’s son Cooper Hefner also mentioned Crystal in his tribute to his father, posted on Twitter on Thursday.

Besides being a model, Crystal is also a singer, a travel blogger, and an advocate for Lyme disease awareness.
