Crystal Hefner, Then and Now: Has Hugh Hefner's Wife Changed Over the Years?

Playboy founder's wife looks nearly unrecognizable when comparing photos through the years

Crystal Hefner, is that you?

The 27-year-old Playboy model looks nearly unrecognizable now when compared with a #ThrowbackThursday photo her hubby Hugh Hefner shared on Twitter yesterday.

The Playboy founder posted a sweet snapshot of the couple and wrote, "#ThrowbackThursday: @crystalhefner and I back in 2008– our first Christmas holiday together."

Their five-year-old photograph shows Hef and Crystal sitting next to each other while holding a tiny picture of themselves in a heart frame. Aw! So cute.

However, we couldn't help but notice that the blond beauty looks a little…different.

And Hefner has been posting a number of selfies on Twitter lately, so we've seen plenty of recent pics of her face.

Regardless, Crystal looks as gorgeous as ever, and recently shared her adorable Christmas card with Hef, that shows the pair looking cozy with their adorable Cavalier King Charles Spaniel, Charlie, as they pose for this year's holiday card.

Hef, 87, wore a silky red robe as he cuddles up to his lady, who dons a matching nightgown in pink. The card reads, "Season's Greetings" and is signed, "Hef, Crystal + Charlie [pawprint]."
