Hef was all set to marry Crystal Harris earlier this summer before she called it off just days before the big day. It obviously wasn’t the smoothest split, and recently Hef even blasted her on Twitter, insinuating there was someone else. And it looks like that’s turned out to be true! Find out who the bosom blonde is shacking up with after the jump..

Crystal Harris has got a brand new roommate — except this time, it’s not an 85-year-old man … it’s Dr. Phil’s son Jordan McGraw.

Sources close to Crystal tell TMZ, she officially moved into Jordan’s Hollywood Hills home a couple weeks ago — but she’s been crashing at the place on and off for months … while she split her time between L.A. and San Diego.

Surprisingly, we’re told the two are NOT dating — they’re just really good friends … and as we previously reported, they’re both working hard to produce Crystal’s new album.

But according to sources, neither Crystal nor Jordan is opposed to a relationship — the prevailing sentiment … if something romantic unfolds, so be it.
