Sure, it might seem as though Crystal Harris is just using Hugh Hefner for fame and attention.
And, of course, one might assume the Playboy founder was only interested in sex with a much younger blonde.
But Harris tells E! News that her and Hefner actually have a lot in common. Like a passion for fun!
"We were both psychology majors in school... We laugh a lot together. We watch movies together. We love relaxing and having a good time and hanging out with the girls. We just keep it fun."
How did we ever doubt this couple? It's like a match made in busty heaven.
On October 11, fans will learn even more about this pair, as they star alongside Karissa and Kristina Shannon in a new version of The Girls Next Door.
What should viewers expect to discover about the young women that make love to such an old man?
"We're the wild ones and party animals, and Crystal's really calm and mellow," said Karissa, while her sister added: "We don't like the peacocks here. They poop everywhere, and they're loud."
That doesn't make them so different from Hef, does it?
